Alien# or Admission#?

hey guys!

I just landed a full-time job as a executive assistant for the CEO of an advertising company, and I have to fill out the I-9 ( Employment Eligibility Verification) form, the box I have to check off is the one that reads "An alien authorized to work( Alien# or Admission#). I was wondering which number are they referring to? the USCIS# in EAC or the number that starts with EAC?
Help please?

The number that starts with "A"

there's no # that starts with A, only starts with EAC or there is another one that says USCIS#

The EAC number is your case number. Check your approval letter, bio appointment letter or acceptance letter. The alien number is in all USCIS documents! Know that number!!!

I got ti! Thank you so much for your help.

You are welcome!!!!!!!!! Congrats by the way for your job!!!!!

I'd hate to have that job l basically the CEOs bitch who picks up their laundry. But congrats anyway lol best of luck

Avoiding those job like the plague, but that's all they have. Ugh

And actually, just to clarify, your eac number is your alien number. Your receipt number becomes your card number, they are not the same. Just add an A before the eac # and that's your "alien number"
