I dont see any difference between eb2 and eb3 now . For eb3 its oct14. I am planning to tell my company to file me in eb3 ( i dont have salary in 60s only mid 50s in civil engg) so eb2 might be difficult. If there's no audit. And perm is approved say at the last week of EAD ( mine expires feb 16) yes am in opt extension, or in grace period ( i guess i have 2 months of it to leave country) . Can I file concurrently and leave the country And come back if it gets approved. Or once i concurrent ly file am i eligible to stay on pending status(140 and 485). ( i know i need ead to work).
I would really appreciate if anyone has some info regarding my queries.
