I have a question regarding changing jobs multiple times after I-485 pending >180 days. Last year I quit from the company that submitted my 140 petition and joined another company. After that move I received RFE from USCIS then submitted AC21. I attended an interview this March and passed; I received a letter afterwards saying my case as "waiting for visa quota". In April I was laid off by the new employer but found another job with similar duties in June. I haven't notified USCIS about this for about 2 months now. Do I need to do that? Please help!
I see no restriction in law preventing multiple job changes. In most cases, I like to inform USCIS, but speak with your lawyers.
