What to do if…
you are asked to show proof of the purpose of your trip and your supporting documents are not accessible

Short answer

Stay calm, tell CBP exactly why you can’t access the documents, and ask if you can quickly retrieve them (Wi-Fi/charger/login). If you can’t, provide verifiable details and ask what minimum evidence they need to confirm your purpose, ability to pay, and intent to depart.

Do not do these things

Don’t lie, guess, or “fill in” missing details — inconsistencies can trigger more scrutiny.
Don’t present altered screenshots, forged letters, or someone else’s documents.
Don’t argue or make jokes about enforcement or inspections.
Don’t delete messages/files or start changing accounts while being questioned.
Don’t refuse instructions out of panic — if you’re unsure, ask what’s being requested and what happens next.

What to do now

State the access problem plainly and early.
Example: “My hotel and return flight confirmation are in my email/cloud, but I can’t access them because my phone has no charge / I’m locked out / there’s no signal.”
Ask if you may try a quick, contained fix.
Ask if you can connect to airport Wi-Fi, charge your phone, or take a moment to complete a login/password reset. If they say no, move on without arguing.
Provide alternative proof you can give without opening files.
Offer concrete, checkable details:
- where you will stay (address + phone number)
- who you’re meeting (full name + phone number + relationship)
- return/onward travel details (airline, flight number, date)
- how you’ll pay (cards; ability to show funds if you can access banking)
Use a “resend/verify” option that doesn’t depend on your phone storage.
Ask your hotel/host/employer/relative to email a short confirmation (dates, address, contact number). If your email is inaccessible, have them send it to:
- a backup email you can open via webmail, or
- a travel companion who can show it
If you’re referred to secondary inspection, switch to “slow and consistent.”
Secondary inspection is used to verify information without holding up the primary line. Keep your answers aligned with what you already said: purpose, length of stay, where you’re staying, how you’ll fund it, and when/how you’ll leave. If stress or language is an issue, ask to slow down or request an interpreter.
If CBP asks to inspect an electronic device, stay calm and ask what they need to verify.
CBP states it has authority to search electronic devices at ports of entry. If you’re a non-U.S. citizen seeking admission, refusing to provide access can affect admissibility decisions. If you’re a U.S. citizen, you generally must be admitted, but you could still face delays or device retention depending on circumstances. If you’re uncomfortable, ask whether providing the specific document(s) by email (hotel/airline confirmation) would satisfy what they’re trying to verify.
Keep all paperwork and note what you were told.
If you’re given written instructions or any notice, keep it. If you’re told to follow up, write down the exact requirement and any deadline.

What can wait

You don’t need to prove your entire life story right now — focus on the basics: purpose, accommodation plan, ability to pay, and intent to depart.
You don’t need to book new flights/hotels while you’re being questioned unless CBP tells you it’s required.
You don’t need to make big decisions in secondary inspection — your job is to stay steady and provide verifiable facts.

Important reassurance

A dead phone, broken login, or missing download is a very normal travel failure point. The most helpful thing you can do is stay consistent, make a practical attempt to retrieve proof, and avoid panic actions (arguing, improvising details, or deleting information).

Scope note

These are first steps for the moment you’re being questioned at a U.S. port of entry. If you’re denied admission or have prior immigration complications, you may need specialist immigration advice afterwards.

Important note

This is general information, not legal advice. Admission decisions at the border are fact-specific and discretionary for noncitizens. If you don’t understand a question or instruction, ask for clarification and take a breath before responding.
