[Q] What is the current procedure for Attorney change of address?
This question was answered on May 10, 2010 during the Central Florida Chapter – Orlando USCIS Liaison Minutes as follows:
In order to change address at the local USCIS Orlando office, the attorney needs to write a letter stating their new address and attach a copy of their bar card. In order to change the address at USCIS service centers, the attorney will have to file a new Form G-28 for every client. Currently, there is no procedure for attorneys to file one form and change address for all clients.
Sure wish there was that one "magic" single G-28 form which would change address for all cases under the Attorney's representation!
