USCIS immigration forms
The United States Citizenship and Immigration Services (USCIS) issues a number of forms for people to submit to them relating to immigrant and non-immigrant visa statuses. These forms begin with the letter "I". None of the forms directly grants a United States visa, but approval of these forms may provide authorization for staying or extending one's stay in the United States as well as authorization for work. Some United States visas require an associated approved USCIS immigration form to be submitted as part of the application.
