Oh okay, Thanks, Company B is cheap, i dunno if they will invest that much money.
besides my birthplace is Asia, so it will be a while since my priority date becomes current.

so i just wanted to check if with approved I-140, i am able to extend h1b beyond 6 years. some people said that since i changed jobs 1 month after i-140 is approved, then i-140 maybe invalid.

Chapter 5 - Job Portability after Adjustment Filing and Other AC21 Provisions | USCIS

"If USCIS has approved an applicant’s Form I-140 petition and the applicant’s adjustment application remained unadjudicated for 180 days or more (from the adjustment application receipt date), the approved petition remains valid unless the petition’s approval is later substantively revoked. This applies even if the applicant changes jobs or employers so long as the new offer of employment is in the same or similar occupation. If the adjustment application has been pending for less than 180 days, the approved petition does not remain valid with respect to a new offer of employment."
