GC start

[satyab.2002]

Hi,

I am on H1b and I-140 is approved is by Employer A. Right now, I am planning to transfer to Employer B. I just have SRC number of I-140. I dont have any copy or anything.

My Question is with my SRC number of I-140 with Employer A,, Can I start GC with Employer B and use the same priority date of my old GC?

Please, let me know. this is very urgent

Thank you in advance
