What is Form I-485 Supplement J?
Form I-485 Supplement J confirms a bona fide job offer or requests to port an employment-based adjustment case to a new, same-or-similar job under AC21.
It is processed with the pending I-485 rather than as a standalone case, so the underlying adjustment case is what to track for real movement.

Can I track Supplement J separately?
Not usually — it is adjudicated with your I-485. Track the I-485 for movement.
When do I file Supplement J?
Commonly when changing employers under AC21 with an I-485 pending 180+ days. Confirm eligibility with an attorney.
