My fiancé (US citizen) and I (F1) will get married in the city hall soon and start GC application. My fiancé has been a student for the last 5 years. His income, including scholarship and some gig payments by personal checks, doesn't meet poverty guideline threshold. He also never filed the tax because it's less than what's required to file tax return. He has no loan but some music instruments (cellos and bows) that worth $100,000 can be certificated and about 20,000 saving in bank. Can those be counted as "assets"? Will the absence of tax-filing affect the application? We have his parents (both work for government and his dad in military) as our cosponsors. But can they take full responsibility (affidavit of support) for me? We plan not to have the reception to save money. Will the city hall wedding be enough to show with other evidences? Thanks!
