Help Filling out my I-90 (Replacement Green Card) form.?

Question

I went to US Immigration today and got my Alien Registration # so i can fill out my replacement form.

The lady gave me my A#, and other info such as, POE (Port of Entry), DOE (Date of Entry) and COA (?).

I filled out the form and I'm kinda stuck on some areas, I really want to fill this out properly because I am joining US Air Force, and I really don't want to be delay any longer (green card usualy takes 4-6 months to be processed).

The I-90 form is located here:

I'm just wondering what/where is COA on this form. The lady at the immigration wouldn't give me that info if I didnt have to put it on the forum. She wrote on the piece of paper "COA = IR2"... I looked that up, I couldn't find anything online...

Answer 1

I would guess either City Of Approval or Category Of Approval. I'm thinking more towards Category Of Approval since IR2 means Immediate Relative 2nd preference.

Answer 2

COA means class of admission. IR-2 means Child of a U.S. citizen. Apparently, you have a parent or a step-parent who is a U.S. citizen, and that person petitioned for you. You arrived with an immigrant visa issued based upon that approved petition.

The I-90 does not ask for COA.
