No. International students, meaning citizens of another country wishing to enter the United States for the purpose of attending a university, can legally do so only with a visa. There are many types of visas. International students almost uniformly hold either an F or a J visa. These do not permit an international student to remain permanently in the United States; they must leave when their enrollment ends. Among the nine criteria that must be satisfied by a student to obtain in-state status is the " . . . legal ability under Federal and Maryland law to live permanently without interruption in Maryland." International students do not have this legal ability. Also, virtually all international students are residing in Maryland primarily to attend an educational institution. Please note, UMGC does not sponsor F-1 visas.
International students should not be confused with the broader class of students who simply are not citizens of the United States. The university enrolls many resident (or "immigrant") aliens. Many have lived in the United States for a considerable period of time. They, like U.S. citizens, have the legal ability to live permanently without interruption in Maryland. They can be eligible for in-state status.
The university also enrolls many nonresident (or "nonimmigrant") aliens. Nonresident aliens living in the United States must hold visas. They have been admitted for many different and specialized purposes. Some types of visas are as restrictive as the F and J visas, but others are not. Depending on the type of visa, a student from a foreign country could well be eligible for in-state status. The Attorney General of Maryland has made a determination for each visa type.
