The U.S. federal government agencies that handle immigration matters are notoriously overworked. It’s not uncommon for them to lose, or at least misplace, pieces of a foreign national's application (such as a photo or copy of a birth certificate) or the entire thing. (These agencies include the Department of State (DOS), U.S. Citizenship and Immigration Services (USCIS), Customs and Border Protection (CBP), and others.)
The problem is made worse by the fact that you can't submit immigration applications in person. They must be either mailed or sent digitally, whether it's to USCIS, a consulate, the National Visa Center, or some other office. So you can’t have someone confirm, in front of your eyes, that everything is complete and ready for review.
Let's take a closer look at how to deal with mislaid applications within the immigration bureaucracy.
Don't panic if you don't receive agency action right away. You can pretty much expect weeks, months, or sometimes even years of delays in the progress of your immigration application. That's "normal," and it times it gets even worse than normal. In 2025, for instance, USCIS is experiencing record-high case backlogs owing to increased application volume, staffing shortages, and stricter case-review and vetting standards.
Such slow movement can be both frustrating and expensive—if, for example, the agency considering your application writes you a letter saying that you forgot to send a doctor's report on your required medical exam and must send it now for your application to be processed, when you know perfectly well you included the report in the envelope.
There’s nothing you can do to completely prevent such problems, but the following four tips will help:
When you have finished filling out a packet of required immigration forms for the benefit you seek, your first instinct might be to seal it all up in an envelope, pop it in the mail, and get on with your life. That could waste all of your hard work.
You will want to make photocopies of every page of every petition or application, as well as any photos, documents, declarations, and other items. Everything.
Carefully keep these copies in your records. They could come in handy later, at the least to help convince USCIS or the consulate to take another look for the lost items. In some cases, applicants have ended up supplying USCIS with a photocopy of the originally filed application, which then becomes the primary one kept in their file, to replace the lost one.
The sorting of newly arrived applications by U.S. government clerks seems to be a common time for items in an immigration application to disappear. In this situation, it can become important to prove that you mailed it in the first place.
In the United States, one option is to go to the post office and use certified or Express Mail, which includes online tracking and signature proof. It might cost more, but considering the importance of these documents, now is not the time to save every penny.
Another option—and your only option if you’re mailing something from outside of the United States—is to use a courier service such as FedEx or UPS. However, courier services can’t deliver to a post office box, so be careful to look for the alternate address for delivery by courier, shown for each type of form on the USCIS website at www.uscis.gov.
Finally, if you have the technology available to you, seriously consider filing online. The scanning of documents can be a bother, but you'll get instant confirmation, and won't have to worry about losses in transit. Not all U.S. immigration forms offer e-filing as an option yet, but it's an attractive one when available.
Many immigration applications require that, if you're filing by mail rather than online, certain personal documents, such as birth, death, divorce, or marriage certificates, be attached. (Paperclipping them to the main form is fine.) Some documents must be included in packets of forms you must file and others must be brought to in-person interviews. Whatever you do, however, don’t send originals to USCIS or the consulate unless you are absolutely sure that this is all they will accept.
Instead, simply photocopy any document (as long as the original is the official version), and send the copy to USCIS or the consulate. The USCIS or consular officer will ordinarily have a chance to view the originals when you later bring them to your in-person interview. (Of course, if they make a special request that you mail them the original, you’ll want to comply—but make copies for yourself first!)
It’s best to add the following text, right on the front of the photocopy, if there’s sufficient room:
Copies of documents submitted are exact photocopies of unaltered original documents, and I understand that I might be required to submit original documents to an immigration or consular official at a later date.
Signature:
Typed or printed name:
Date:
Always make photocopies for USCIS on one-sided, 8 1/2 x 11 inch paper. If the original document is larger than this, you might need to reduce it during the photocopying process.
Keep a close eye on your mail or other communications from the agency in question. Also, if you move or any of your contact information changes, advise the relevant agencies right away.
If something is missing from your application, they're likely to ask for it. USCIS, for instance, might send a document known as a Request for Evidence or RFE, giving you a deadline (usually 30 to 90 days) in which to supply what's supposedly missing. Common reasons for RFEs include incomplete or missing forms, lack of supporting documents, inconsistent information, missing certified English-language translations of foreign documents, and insufficient financial sponsorship evidence (in family visa cases).
The sooner you can learn that your case has been delayed, the sooner you can do something about it. After filing many types of USCIS applications, for instance, you can expect a receipt notice (Form I-797C) within around four weeks. This will contain a 13-character receipt number, with which you can track your application's status through USCIS's Case Status Online tool, or by calling their Contact Center at 1-800-375-5283.
If the above steps don't help get your application back on track, you'd be wise to hire an experienced immigration attorney to help. Because processing problems are common, the attorney will know who to contact and how best to track down what's missing. See Is an Immigration Lawyer Worth the Cost?.
