USCIS Form Guide: What You Need to File and What Holds It Up

Short answer: pick the form you are filing and this explains, in plain language, what it is for, what documents you will be asked to produce, what usually causes delays, and what to ask a lawyer. It does not quote a filing fee or a processing time — those come straight from USCIS, and we link you to the official page for your form so the number you get is today’s.

Fees and processing times — always from USCIS

We do not republish filing fees or processing times anywhere on this page, on purpose. USCIS issued a new fee schedule on 9 September 2026, and any figure copied onto a website is wrong the moment the next one lands. These links go to the source.

Common questions

How much does it cost to file this form?

Check the USCIS Fee Calculator rather than any figure you read on a law firm’s website, including this one. USCIS changes filing fees, most recently with a fee schedule issued on 9 September 2026, and a page that hardcoded a number last year is quietly wrong today. The calculator is the official source and it is free to use.

How long is USCIS taking right now?

It depends on the form and on which office or service centre is handling it, and it moves month to month. USCIS publishes current processing times and updates them monthly. A published time is a median, not a promise — half of cases take longer.

Why is my case taking longer than the published time?

The most common reasons are a Request for Evidence, a missing or inconsistent document, a name or date that does not match across filings, a background check that has not cleared, or a transfer between offices. A case outside normal processing time can be raised with USCIS through a service request, and that is worth discussing with a lawyer before you file one.

Do I need a lawyer to file a USCIS form?

Not always. Many people file straightforward applications themselves. It is worth paying for advice when there is anything in the history that complicates it — a prior denial, a criminal matter, time out of status, an earlier filing by someone else, or a deadline you are not sure about. The last section of every explainer here lists the questions worth bringing to that conversation.

Is this legal advice?

No. This page explains what forms are for in general terms. It does not know your history and cannot tell you what will happen in your case, which is exactly the kind of question a licensed immigration attorney should answer.

If you run an immigration firm

This page exists because the questions on it get asked hundreds of thousands of times a month, and almost no firm answers them in plain language on their own site. We build this tool with your firm’s name on it, your branding, and your consultation form at the end of every answer.
