hi, my employer filed for my I-140. not approved yet. now my end client offered me fulltime. will that mess up my application for I-140? do i need to change employer? if yes then what about my priority date? will it stay the same? should i take this offer? i spoke to my company that i will need a sponsor n they r working on it. dont know what they will come up with. what other questions should i ask. please,,, if anyone knows.....
