All I-485 Applications for adjustment are filed at remote USCIS Service Centers in the U.S. The processing time may take a few months. While the processing time for Consulate processing time at the U.S. Consulates will also take a few months.
If you are in the U.S., the I-485 is sent to a certain service center depending on the state in which you currently reside and the process in which you are applying for. The processing times vary and cannot be guaranteed, but can take several months for processing.
