Hey Guys, my EAD expires on April of next year so i am between the 150-120 days of expiration timeframe so im sending my renewal package this week. I have a question regarding form I-765. On question 11 it asks which USCIS office approved my case plus the date. I lost the letter of approval from when my ead was renewed last year . How do i find this info if i dont have the letter ? my EAD card shows LIN for card number. Does that mean anything?
