it is not as easy it sounds ..read this..
It is not easy to use LC approved for somebody else. I won't do it unless I am desperate ( 6yrs expiring ) to survive.
The education, skillset, experience everything should match most, 80-100%.
If the original LC is not with the company/attorney, DO NOT DO IT. It is going to take cool two years. Because original LC might be with DOL ( not BCIS/INS). BCIS/INS need to request DOL and get it from them while processing the case.
If the original LC is with the company now, you may go for it and wait until EAD/AP are approved. That way, there are chances that they reviewed your info with the approved LC. I would wait until EAD is approved to switch jobs.
If the sponsoring company is willing to pay for it, go for it.
Ofcourse, we cannot prevent anything from happening. Good Luck.
