According to a recent Murthy article:
I have not fully understood what happens when an applicant keeps porting using AC21 through multiple jobs. I don't think the law requires you to file Supp J proactively. However, you need to have a current Supp J at the time of approval of I485 (when the PD becomes current). Now most attorneys suggest not filing Supp J. Ours did, however We forced them to do it for personal reasons.Quote:
The supplement J may be filed proactively by the beneficiary at any time. If not, prior to approving the I-485, the USCIS should issue a request for evidence (RFE) or notice of intent to deny (NOID) to request an updated supplement J.
Arguments *for* Filing I485J proactively after switching:
1. The company agreed to it when you accepted the job and they will do it at their own cost. No delaying business.
2. You do an updated I693 (Medicals). Keep medical documents up to date.
3. In 6 months, you know whether I485J was approved. If it was denied for any reason, you have time to file a PERM and port the date within 1.5 years of accepting the offer.
Arguments *against* filing I485J proactively after switching:
1. You can port using AC21 from Company A to B to C to D. All you need is to file Supp J for company D.
2. Current political climate is not conductive to smooth passing. However, I have not seen any I485J denials. This point may be moot.
3. Multiple attorneys are discouraging this option. I have not obtained a good explanation. It may not be that rewarding (financially for them) or they might want to save money for the company.
