863211, I have an urgent question about interfilling

863211,

My case is Eb1_b and my hu*****and case is EB3. My EB1b I 140 was approved in Texas center and our 485s are in Nebraska center. I make the call the nebraska center to request interfilling and the supervisor told me they could not do that because I am not the petitioner or employer.

Question1: Should I find an attorney to do that?  Or I need to go to the School office to ask them to make a phone call to nebraska center?

Thanks in advance!
