Premium Processing Availability for Second I-140 Filing
When a second I-140 is filed, is Premium Processing available?
When a subsequent I-140 is filed by a successor-in-interest, USCIS can
accept the Premium Processing request only if it has access to the original
ETA 9089 PERM Approval. If the USCIS cannot get access to the original, the
Premium Processing will be rejected.
To upgrade an I-140 filing that is in regular processing, the applicant must
submit the I-907, the appropriate filing fee, and a copy of the I-140
Receipt Notice to the USCIS Service Center that has the I-140 petition
pending. If there is an attorney representative on the I-140, a G-28 must
also be submitted.
