Losing your passport or immigration papers is stressful, but every document can be replaced. Act quickly and in order.
Search carefully: bags, car, work, the last places you visited. Call the airline or transit lost and found.
If stolen, report it to the local police and ask for a copy of the police report. Many consulates and offices ask for it.
Find your copies: photos on your phone, cloud folder, emailed scans. Copies make replacement much faster.
Remember that adults must carry proof of registration. Until you have a replacement, carry a copy of your I-94 and the police report.
Only your own country can replace your passport.
Contact your country's embassy or consulate in the US. Look on its website for "lost passport".
Usually you need: the police report, a form, photos, proof of identity (copies help), and a fee.
Ask if they can issue an emergency travel document if you need to travel soon.
A visa stamp in a lost passport cannot be replaced inside the US. Your permission to stay is shown by your I-94, not the visa. You will need to apply for a new visa at a US embassy or consulate the next time you travel abroad and need it. Report the lost or stolen visa to the US embassy or consulate that issued it, following the steps on travel.state.gov.
If you entered by air or sea recently, your I-94 is electronic. Download it again at i94.cbp.dhs.gov with your new passport details or the old passport number.
If you have a paper I-94 that was lost, apply for a replacement with Form I-102 at USCIS.
File Form I-90 to replace a lost, stolen or damaged green card. You can file online. Keep the receipt notice, and if you need proof of status urgently (for travel or work), contact USCIS for an appointment to get temporary evidence.
File Form I-765 for a replacement card. Fees apply; check the current fee on the form page at uscis.gov.

Tell your DSO or RO (international office) right away. They can help with letters and the next steps for your I-20 or DS-2019.
Keep your passport at home in a safe place. Carry the I-94 or a copy of what the law requires.
