Entry into the United States is a highly regulated process, and there are also quotas in place to control the flow of immigrants into the country. Working through that process can be a challenge, but an immigration attorney can guide you through it. It helps to understand the ways that immigration into the U.S. is commonly allowed so let's take a look at four of the most common.
Two primary groups of people are eligible to seek work visas in America. First, there are individuals who have special skills that are in short supply. Second, there are folks who are considered intracompany transfers, meaning they've been moved from one corporate location overseas to another in the U.S. Both require the worker to be sponsored by a company. Notably, individuals with most other types of legal visas, such as green cards, are legally allowed to work without filing additional paperwork.
If you're enrolled in a program with a U.S.-based institution that will lead to a degree being conferred upon you, a student visa is the way to go. Recreational study that does not lead to a degree can be conducted under a visitor visa. You must attend a school that is approved as part of the Student and Exchange Visitor Program. Academic and language training papers are granted under the F visa program, while vocational training is granted under the M visa.
Four groups of people are eligible to immigrate to America based on familial relationships. Anyone married to a U.S. citizen may apply for a visa, as can any children under the age of 21 who were born to at least one U.S. citizen. Orphans from abroad who are to be adopted by a U.S. citizen can apply, too. The parents of a U.S. who is at least 21 years old may seek visas, also.
If you are someone who the U.S. government classifies as an individual with "extraordinary ability or achievement," you are welcome to apply for what is called an O-1 visa. These are granted to people who excel in scientific, artistic, athletic, educational and business pursuits.
The O-2 visa is also available, and this applies to people who'll accompany such individuals, including personal and production assistants. It must be shown, though, that the job of the assistant cannot be performed by an American. O-3 visas are also available for spouses and children of O-series visa holders.
