Legal Question in Immigration Law in Ohio

As the visa petitioner, you do need to also file an affidavit of support. You must be able to show sufficient income or assets to support your household. This is done by measuring your household size against the federal poverty guidelines and your income. If you do not have sufficient income, your spouse's income can be attributed so long as it was gained lawfully (and in this case it sounds as if it has as there is an H-1B visa noted). If, between both incomes, you fall short of the poverty guidelines, you can get a co-sponsor.
