Family-Based and Individual Immigration
Non-Immigrant visas are an option for persons who want to travel to the U.S. on a temporary basis such as for business, tourism, to study, to work temporarily, among other reasons. These visas are issued for a specific length of time and for specific purposes.
The "green card" is proof of legal permanent residence in the U.S. and allows a person to live permanently in the U.S. and to work in the U.S. Most green card holders are sponsored by a family member or employer in the United States. Humanitarian programs offer another option, and in some cases you may be eligible to file for yourself.
