My previous employer didn't pay me for 7 continuous months in 2006, Current employer is going to file I-140 and I-485 based on my EB2 PERM. I have all W2 and Pay stubs except that period. will that going to affect my GC application ? Please let me know what are the possible consequences of that. I didn't know about that 180 days rule.
Pursuant to section 245k of INA, an employment-based applicant and their family can file for an AOS (I-485) if they have been out of status or have worked without authorization for less than 180 days. The protection period is counted since the date of your most recent entry into USA. So if before filing I-485, you leave USA and reenter, you should have no issues. There are other ways to fix this also, but this is the most direct.
See attached USCIS Neufield Memo of 14 July 2008.
