I am filing my I-140 and I-485 (concurrently). I just noticed that the filing addresses are different for filing I-140 and I-485. I am supposed to file my documents to Texas Center. Based on USCIS website, “For Form I-140 alone, or concurrently with Form I-485, Application to Register Permanent Residence or Adjust Status, mail your forms package to: USCIS Texas Service Center, P.O. Box 852135, Mesquite, TX 75185” (Form I-140 Instructions, page 5). However based on the I-485 Instructions (pages 5-6), the mailing address is: USCIS Texas Service Center, P.O. Box 851804, Mesquite, TX 75185. Plus, for Forms I-765 and I-131, the filing address is the same as for Form I-485 if concurrently file with I-485. So I am kind of confused, since I am concurrently filing I-140, I-485 as well as I-765, I-131, where am I supposed to file all these documents? I appreciate your time and kind answer!
