I am trying to find in which USCIS service center my application will be forwarded from Phoenix AZ lockbox. I am US Citizen living in California, looking to fill I-130 for my wife. I have not started my application yet. I am planning to fill application soon. before I do, I am trying to find all the details. Is there a way to find which USCIS service center will process my I-130 application if I filled online or by mail to Phoenix AZ lockbox location? It’s very important for me to find this out as service centers has a different wait time. Can someone plz advise?
Thanks in advance.
