I-485 receiving facilities and receipt numbers:
1: If you filed I-485 without I-140 to the USCIS Phoenix Lockbox, your case would likely be assigned a receipt number MSC2190XXXXXX, and forwarded to and reviewed by NBC.
// We currently see quicker progress for this center compared to the Dallas Lockbox. As of 01/26/2021, the Phoenix lockbox is processing packages received in early December, 2020.
2: If you filed I-485 without I-140 to the USCIS Dallas Lockbox, your case would likely be assigned a receipt number MSC2190XXXXXX, and forwarded to and reviewed by NBC.
3: If you filed I-485 and I-140 concurrently to the USCIS Dallas Lockbox, your receipt number will be LIN2190XXXXXX or SRC2190XXXXXX depending on your employer location.
// We currently see slower progress for all the filings at the Dallas Lockbox. As of 01/26/2021, the Dallas lockbox is still processing petitions received in late October, 2020. Some reports indicate that the Dallas Lockbox is sending packages to the Chicago Lockbox for data entry, as people reporting their credit cards / checks transactions being processed in Chicago although the package was delivered to Dallas.
4: If you filed I-485 and I-140 concurrently with premium processing (aka. PP), it would go to the service center directly and not through a lockbox facility. Your receipt number will be LIN21xxx5xxxx or SRC21xxx5xxxx.
