Part 3, Question 2 on Form I-90, Application to Replace Permanent Resident Card, asks about the “location where your immigrant visa was issued or USCIS office where you were granted adjustment of status.”
Location Where Your Immigrant Visa Was Issued
If you applied for and were granted an immigrant visa while outside the United States, you immigrated through consular processing. The location where your immigrant visa was issued is the “City, Country” of the U.S. Embassy or consulate where you had your interview. Although you didn’t receive a green card until arriving in the United States, the location where your immigrant visa was issued is the location that you became a lawful permanent resident.
USCIS Office Where You Were Granted Adjustment of Status
If you filed an Application to Adjust Status (Form I-485) because you were already in the United States, this is the location of the USCIS office that granted you lawful permanent residence. Although you probably received your green card by mail, the USCIS office where you were granted adjustment of status is the location where USCIS conducted the interview (and probably informed you of the approval). Enter the “City, State” of the USCIS office location.
You can also find the USCIS office where you were granted adjustment of status by reviewing your green card. Look for the card# (application receipt number) on your card. This is a hidden code that may be on the front or back of your green card, depending on the year it was issued. The first three letters are a code for the USCIS office that granted your adjustment of status case.
