I want to know if I can fix my husband papers if I’m a USA citizen

OK so if you are a US citizen, and you married your husband who is a foreign national, then you can sponsor him for a green card provided that he entered the United States with a visa. If he crossed the border without permission or without a visa, then you can still sponsor him but you are going to need a waiver. Consider working with an attorney to handle your paperwork. Some of his charge a very affordable flat fee, with no hidden costs, and process the case from beginning to end, which takes about one year. My office handles cases in every state in the country and cases all over the world.
