In Jan 2023 my wife & I filed our I751. In a cover letter I explained to USCIS that my wife & I had long ago decided that we would not mingle our assets, past or future and that neither of us had any debt to share. Therefore we would not be able to furnish any of their suggested documents of shared responsibility for indebtedness. We did furnish several documents I thought should be sufficient to lift the restrictions including our marriage documentations which (as of this writing) are currently almost 5 years old. That's right, we've been married and living in the same house every day for almost 5 years. In Sept 2024 we received an RFE requesting the same documents we were unable to provide with the original filing. It sounds to me like they are requesting us to open joint accounts and create joint loans so as to be able to provide documents to prove their existence. I really don't know what else to do. I'm hoping someone here has some better ideas. Thanks for listening. BTW, the RFE is from the service center in Irving, Tx, not California.
