My Eb2 485 was filed one and half year ago and my priority date is April 2005. My hu*****and is going to concurrently file Eb1B 140-485. Should I join him now or after his I-140 get approved ? Can I file two I-485? Can I relink my I-485 case to his I-140 or I have to refile my 485 case after his I-140 get approved? Thanks a lot for your suggestion/answers.
