How do I change address? Please help!

[calmdown]

I am moving to another state so I need to change my address on my pending I-485 file. Please help me with a few questions. Many thanks!!!

1) How do I change my address on I-485 file? Do I need to call or fax my address to USCIS? What's the CSC fax number I should use? Can I do it myself or I should have my attorney do it?

2) Can I use a P.O.Box or the company address for I-485 purpose? Will it cause any problem if the I-485 address is different from the address on my AR-11 form?

3) Will the address change trigger a RFE? Is it better if I file AC21 before changing address?

Your response is much appreciated!

1) How do I change my address on I-485 file?

Do I need to call or fax my address to USCIS? What's the CSC fax number I should use? Can I do it myself or I should have my attorney do it?

----- You should mail the Form AR11. Also update the NCSC on phone # 18003755283, better update with your I-485 filing receipt, if EAD, AP also filed provide the receipt # of all the pending applications so that they should change address for all pending applications.
You should also send a letter to your service center and request the change of address for all pending applications, attach the copy of I-485 filing receipt, EAD filing receipt, AP filing receipt and write your past address and new address, your complete name, DOB, and your A # ( A# will be on I-485 filing receipt check the receipt it is written right side) and out side the envelope write in big bold letters “ Attention: address change” send this letter to service center with certified return receipt mail. I don’t know the CSC Fax#


2) Can I use a P.O.Box or the company address for I-485 purpose?
---------- It has to be your residence address. P.O box is not advised for mail from USCIS.
Will it cause any problem if the I-485 address is different from the address on my AR-11 form?
------------ It should be same
3) Will the address change trigger a RFE?
-------NO
Is it better if I file AC21 before changing address?
------- Better file AC21 after changing the address, so that if they have not changed the address they will change the address when you send AC21 letter and your new address
