My husband and I are filing for that. I am submitting an application for him and one for me. Do I need to submit one for our 7 year old too (and hence pay 275 USD for the three of us)?
Everyone need a separate application and fees. Just ensure that you qualify for the returning resident visa, the fees are non refundable.
A follow up question, I went to the designated bank where I can pay for US immigration applications and the Bank said they do not take money for that form. This is the Application to Determine Returning Resident Status. Do I not pay when i send this application, and pay later? Or am I supposed to pay right away and there is some kind of misunderstanding about how to pay the 275 USD per application?
