My green card was approved through employment ( I am a 245i benefitiary). I worked for the company that was sponsoring me for 4 years. Right after getting i-140 approved, they laid me off. I was supposed to go back to them after the GC was issued but the crisis hit and once my gc was approved I showed up to work (my AOS processin lasted only 90 days).
One week after my GC was approved they gave me a letter saying the position was being eliminated due to slow sales.
I went to work for another employer and alas! 5 years went by and now I want to become a USC.
Should I wait a couple more years so my sponsoring employer is not listed on the application? I can wait. I just do not know if they always ask you about the sponsoring employer on the interview or not.
