You're Under Federal Investigation — What Happens Next (And What to Do Right Now)

Something just happened. Maybe it was the FBI at your office door. Maybe it was a letter from the U.S. Attorney's office. Maybe your accountant called and said federal agents showed up asking about your business. Maybe your partner was just indicted and now you're wondering if you're next.

Whatever triggered it — you're here now. And the next 48 hours matter more than you think.

Here's what's actually happening, what the government is doing behind the scenes, and what you need to do right now to protect yourself.

First: Understand What a Federal Investigation Actually Is

A federal investigation isn't a traffic stop. It's not a local detective asking you some questions and deciding whether to file charges. Federal investigations are slow, methodical, and comprehensive. By the time you find out about one, it's been running for months — sometimes years.

The FBI, IRS Criminal Investigation, the Postal Inspection Service, or whatever agency is involved has already been collecting evidence. They've pulled your bank records. They've subpoenaed your emails. They may have been monitoring your communications. They've talked to your associates. They've built a timeline.

When federal agents show up at your door, they're not investigating. They're confirming what they already believe. They're looking for you to fill in the gaps — to say the one thing that ties the bow on their case.

This is not the time to talk. This is the time to stop, breathe, and make the right moves.

The Target Letter

If you received a target letter from the U.S. Attorney's office, understand exactly what that means.

The DOJ classifies people in federal investigations into three categories:

Witness: You have information relevant to the investigation, but you're not suspected of criminal conduct. You may be asked to testify before a grand jury.

Subject: Your conduct falls within the scope of the investigation, but the government hasn't decided whether to charge you. This is the gray zone. You might end up a witness. You might end up a defendant.

Target: The government has substantial evidence linking you to a crime and is likely going to seek an indictment. A target letter is, effectively, a warning that you're about to be charged.

If you received a target letter, the government is telling you: we're coming. This isn't a bluff. Federal prosecutors don't send target letters casually. They send them because DOJ policy requires it in most cases, and because it gives you a chance to cooperate or present your side before the grand jury acts.

The existence of a target letter means the investigation is advanced. It means a federal prosecutor has already reviewed the evidence and concluded there's enough to move forward. It means a grand jury may already be hearing testimony.

The Grand Jury Subpoena

If you've received a grand jury subpoena — either for testimony or documents — the investigation is actively in progress and the government wants something from you.

Document subpoena: The grand jury is demanding records — financial documents, emails, contracts, business records. You are legally required to comply, but there are limits. Your attorney can negotiate the scope, assert privileges, and ensure you're not handing over more than required.

Testimony subpoena: You're being called to testify before the grand jury. This is a critical moment. You have the right to invoke the Fifth Amendment and refuse to answer questions that might incriminate you. But you must show up — you can't ignore a grand jury subpoena.

Critical detail: If you're a target, testifying before the grand jury is almost never in your interest. Anything you say is under oath. There's no judge in the room. Your attorney can't be in the room with you (though they can wait outside and you can consult with them after each question). The prosecutor controls the questioning. It's their show, and you're walking into it without a referee.

The 48-Hour Playbook: What to Do Right Now

Hour 0-4: Say Nothing and Call a Lawyer

This is not negotiable. If federal agents are at your door, you say five words: "I want to speak with my attorney." Then you stop talking. You don't explain. You don't clarify. You don't say "but let me just tell you one thing." You invoke your right to counsel and you shut your mouth.

Federal agents are professionally trained to keep people talking. They're polite. They're reasonable. They say things like "we're just trying to understand what happened" and "you're not in trouble, we just need your help." Every single word is designed to get you to talk.

Under 18 U.S.C. § 1001, lying to a federal agent is a separate felony — even if you're never charged with anything else. And "lying" includes misremembering, getting a date wrong, or misstating a detail in a stressful conversation at your doorstep. The safest number of words to say to a federal agent without a lawyer present is zero.

Hour 4-12: Hire a Federal Criminal Defense Attorney

Not your cousin who does DUIs. Not your business attorney. Not the guy who handles your real estate closings. A federal criminal defense attorney — someone who has tried cases in federal court, who knows the AUSAs in your district, who understands the Federal Sentencing Guidelines, and who has handled cases like yours before.

Ask every prospective attorney:

• How many federal criminal cases have you handled?
• How many have gone to trial vs. plea?
• Do you have experience with the specific charges I might be facing?
• Who is the AUSA assigned to my case, and have you worked with them before?
• What is your availability for the next 90 days?

The attorney you hire in the first 48 hours may be the attorney who represents you through indictment, trial, and sentencing. Choose carefully. Use our guide on questions to ask before hiring a criminal defense attorney to evaluate candidates.

Hour 12-24: Preserve Everything — Destroy Nothing

This is where people go to prison for obstruction instead of — or in addition to — whatever they were originally investigated for.

The moment you know about a federal investigation, you have an obligation to preserve all potentially relevant documents. Emails. Texts. Financial records. Computer files. Paper records. Everything.

Do not:

• Delete emails or text messages
• Shred documents
• Wipe your computer or phone
• Move money between accounts
• Ask someone else to hold, hide, or destroy anything
• Post about the investigation on social media
• "Clean up" your files

Obstruction of justice (18 U.S.C. § 1519) carries up to 20 years in federal prison. Tampering with evidence or witnesses can add charges that are often easier for the government to prove than the underlying offense. People have beaten fraud charges and gone to prison for the cover-up.

Tell your attorney what documents exist and where they are. Let them advise you on preservation obligations. Do not make any decisions about documents without legal guidance.

Hour 24-48: Map Your Exposure and Start Building Your Defense

With your attorney, you need to answer some hard questions:

What do they likely have? Based on what you know about the investigation — who's been contacted, what records have been subpoenaed, who might be cooperating — what does the government's case probably look like?

What's your realistic exposure? If you're charged, what are the likely charges? What are the sentencing guidelines? What's the mandatory minimum, if any? What's the realistic range based on similar cases in your district?

Who else is involved? Federal cases rarely involve just one person. Who are the co-subjects? Who might be cooperating? Who has already been contacted by agents? Understanding the full picture of the investigation tells you where you fit in the government's theory.

What's the proffer situation? Your attorney should advise you on whether a proffer — a meeting where you provide information to prosecutors under a limited immunity agreement — makes sense. This is a complex strategic decision with major consequences either way. Don't decide this without extensive discussion.

What NOT to Do During a Federal Investigation

People make the same mistakes over and over. Here's the list:

Don't talk to co-subjects or co-targets about the case. Any conversation you have can be characterized as witness tampering or obstruction. If someone involved in the investigation calls you, tell them you can't discuss it and refer them to your attorney.

Don't talk to friends and family about the details. There's no spousal privilege or friendship privilege that protects casual conversations. Anyone you talk to can be subpoenaed to testify about what you said. Every person you confide in is a potential government witness.

Don't make any large financial moves. Don't move money offshore. Don't transfer assets to relatives. Don't pay off debts in unusual ways. The government is watching your financial activity. Suspicious transactions during an active investigation become evidence of consciousness of guilt.

Don't flee. This seems obvious, but people panic. Fleeing is a separate federal crime, eliminates any possibility of a favorable outcome, and guarantees the worst possible treatment from the court if you're eventually caught — and federal fugitives are almost always caught.

Don't ignore it and hope it goes away. Federal investigations don't disappear. The statute of limitations for most federal offenses is five years. For financial institution fraud, it's ten. The government is patient. They will wait until they're ready, and then they'll move.

The Proffer: What It Is and Why It Matters

Your attorney may recommend — or the government may offer — a proffer session. This is sometimes called a "queen for a day" meeting.

In a proffer, you sit down with federal prosecutors and agents and provide information about the alleged criminal conduct. In exchange, the government provides a limited immunity agreement: what you say in the proffer generally can't be used directly against you at trial.

But — and this is critical — proffer agreements have significant exceptions:

• If you lie during the proffer, everything you said can be used against you
• If you testify at trial and contradict what you said in the proffer, the government can use your proffer statements to impeach you
• The government can use information from your proffer to find other evidence (derivative use) — they just can't use your words directly
• If proffer leads to a cooperation agreement, your freedom may depend on the government's satisfaction with your cooperation — a subjective standard

A proffer is not a get-out-of-jail-free card. It's a strategic tool that can help or hurt depending on your specific situation. For a full breakdown of proffers, safety valves, and substantial assistance, read our guide on federal cooperation agreements. Your attorney should be advising you on this extensively before you agree to anything.

The Timeline Nobody Tells You About

Federal investigations are slow. Federal cases are slower. Here's a realistic timeline:

Investigation phase: 6 months to 3+ years. You may know about it for part of this, or you may find out only when you're indicted.

Indictment: The grand jury returns a formal charge. This is when the case becomes public.

Arraignment: Your first court appearance, usually within days of indictment or arrest. You enter a plea (almost always "not guilty" at this stage).

Discovery: The government turns over evidence. In complex white collar cases, discovery can take 6-12 months and involve millions of documents.

Pretrial motions: Your attorney files motions to suppress evidence, dismiss charges, or limit what the government can present. This phase can last months.

Plea negotiations or trial preparation: These often happen simultaneously. Most federal cases — around 90% — end in guilty pleas. But the strength of your trial preparation directly influences the quality of any plea offer. Before you sign anything, read how to evaluate a plea deal. If you're facing wire fraud specifically, our list of 15 questions for wire fraud attorneys covers what your attorney should know.

Trial: If you go to trial, expect 1-4 weeks for a typical white collar case. Complex cases can last months.

Sentencing: Usually 60-90 days after conviction, whether by plea or trial.

From the time you learn about the investigation to the time your case is resolved, you're looking at 1 to 5 years. This is a marathon. The decisions you make in the first 48 hours set the trajectory for all of it.

The Bottom Line

A federal investigation is serious. It's not going to go away because you ignore it, and it's not going to resolve itself because you explain what really happened to the nice FBI agent at your door.

What it takes: silence, a good attorney, document preservation, and strategic patience. The defendants who survive federal investigations — who get favorable outcomes or avoid charges entirely — are the ones who took it seriously from hour one.

Don't be the person who talked when they should have listened. Don't be the person who deleted the email. Don't be the person who waited three months to hire a real federal defense attorney.

The clock started when you found out. The next 48 hours are yours. Use them.
