Two trickly questions from I-90 Application to Replace Permanent Resident Card

My green card (Permanent resident card) is expiring, so I need to file form I-90 to review/replace my green card online.

The first step is to register an online account iwth USCIS at uscis.gov

The second step is to fill out the form I-90

However, there are two questions a bit tricky to answer which are:

Where did you apply for your immigrant visa or adjustment of status?
Where was your immigrant visa or adjustment of status granted?

First off, if you applied green card outside of USA, it is immigrant visa. If you applied while you were in the USA, it is adjustment of status.

Provide the location of the U.S. Embassy, U.S. Consulate, or USCIS office that issued your immigrant visa or permanent resident status.

This info was ten years ago, very hard to recall or identify, however, the green card has receipt number or card # starts with USCIS office code. Using the office code, ask google to find out the office. For my case, the 3 characters are LIN, so it maps to Nebraska Service Center. Questions answered.

The three-digit codes for USCIS office locations are:

• MSC: National Benefits Center
• NBC: National Benefits Center
• EAC: Vermont Service Center (formerly known as Eastern Adjudication Center)
• VSC: Vermont Service Center
• WAC: California Service Center (formerly known as Western Adjudication Center)
• CSC: California Service Center
• LIN: Nebraska Service Center
NSC: Nebraska Service Center
SRC: Texas Service Center (formerly known as Southern Regional Center)
TSC: Texas Service Center
IOE: ELIS (e-Filing)
YSC: Potomac Service Center

The first three characters of a USCIS application's 13-character receipt number indicate which USCIS service center is processing the case. The receipt number can be found on the application.

The first three letters of the card number on a green card also indicate the USCIS office that granted the adjustment of status case. The card number may be located on the front or back of the card, depending on the year it was issued.

To visit a USCIS field office, an appointment is required, and walk-ins are not permitted. The field office address can be found on the appointment or interview notice.
