My I-140 has been approved and I am preparing th I-485 (AOS). My H1B expired on March 4th and my company has aplied for 7th year extension in January with TSC. If they deny the 7th year extension, can I still work for the company since my I-485 is pending..? if not can I stay in the US until I get my EAD and resume work for the same company...?
