What Is Part 1 of Form I-693 (Applicant Information)?
Quick Answer
Part 1 of Form I-693 captures the applicant's identifying information, including full legal name, date of birth, country of birth, and USCIS Alien Registration Number (A-Number). This section is completed by the applicant before the civil surgeon examination begins and must match the information on the applicant's immigration documents exactly.
What Information Is Collected in Part 1?
Part 1 of Form I-693 collects the applicant's full legal name (family name, given name, and middle name), date of birth, country of birth, and USCIS Alien Registration Number (A-Number) if one has been assigned. It also asks for the applicant's current address and the date of the examination. This information establishes the identity of the person being examined and links the medical record to the correct USCIS file.
Who Fills Out Part 1?
The applicant — not the civil surgeon — is responsible for completing Part 1 before the examination. In practice, the civil surgeon's office staff often assists applicants in filling out the form correctly. However, the applicant must verify that all information is accurate. Errors in Part 1, such as a misspelled name or incorrect A-Number, can cause USCIS to reject the form or issue a Request for Evidence (RFE).
Why the A-Number Matters
The Alien Registration Number (A-Number) is a unique nine-digit identifier assigned by USCIS to most non-citizens. Including the correct A-Number in Part 1 allows USCIS to match Form I-693 to the applicant's immigration file quickly and accurately. If you have not yet been assigned an A-Number — for example, if you are filing Form I-485 for the first time — leave that field blank. Do not guess or fabricate a number.
Matching Information to Immigration Documents
All information in Part 1 must exactly match the applicant's passport, visa, and other immigration documents. Even minor discrepancies — such as a nickname instead of a legal name, or a transposed digit in the date of birth — can trigger a USCIS rejection. If your name has changed due to marriage or other legal reasons, use the name that appears on your current immigration documents and be prepared to provide supporting documentation.
Common Errors in Part 1 and How to Avoid Them
The most common errors in Part 1 include using a nickname instead of a legal name, entering the date of birth in the wrong format, omitting the A-Number when one exists, and providing an address that does not match USCIS records. Before your appointment, gather your passport, green card application receipt notice, and any prior USCIS correspondence so you can complete Part 1 accurately. Our staff will review your entries before the civil surgeon begins the examination.
