If your I-485 is pending at TSC then send the AC21 request to the same address of TSC. Your I-485 filing receipt may have the address. Out side the envelope write in big bold letter: Request to invoke AC21 with Pending form I-485.Hi,
I have all the supporting documents for AC21 which I need to submit to USCIS. My case is in TSC.
Where can I find the postal address ?
------------------You can find the I-485 filing address on TSC site.
Thanks,
Mona
Can you please all the documents that you need to send for AC 21.
