Interfiling an approved I-140 petition with an already pending I-485 application
According to the center interfiling requests usually occurs in two broad categories. For the first category, the cover letter and the documentation submitted with the new I-140 must highlight the request for the petition to be matched to the existing adjustment application. The cover letter can be brightly highlighted with the notation "Inter-file I-140 with Pending I-485," which will also include the receipt and file number for pending adjustment application. In the second category of cases where the I-140 has already been approved the center suggests printing the attached cover sheet on brightly colored paper. While submitting a cover letter providing following information can be mentioned:
Name of Applicant
Name of Petitioner
Receipt No. for I-485
File No. for applicant (A number)
Prior I-140 receipt number, with dates of filing and approval
New I-140 to be inter-filed.
Statement requesting new I-140 be inter-filed with the pending adjustment application.
