you don't!

Thanks @Andy Gee. someone mentioned J Supplement form and I don’t even know what that is.

if you filed EB1B catagory (Employer dependent) then only you need to submit new 485J supplement EB1A don’t need to submit anything.

oh okay. Thank you @ss dachavaram

You don’t but it rare cases if you lr I485 get rejected, you wiol be out of status. if you are on H1B visa just transfer it to the new employer.

@ss dachavaram what about EB1C ??

@sat ban No idea about EB1C

EB1C needs an I-485J filed for change of employer during AOS.
