Immigration Q&A: How can I get a visa to live in the U.S.?
There are, however, many types of non-immigrant visas, including trainee ones, that could possibly be suitable for you, including the H-3 trainee visa, which is available for those seeking training in a number of fields, including communications. However, the training that is received must not be available in the person’s home country, and the training must benefit the alien in pursuit of employment outside the U.S.
The H-3 visa, and all of the other visas available, have many kinds of restrictions and requirements. Number one, though – sponsorship of a U.S. employer or organization.
If you are seriously considering relocating here, it would be a good idea to visit to explore your options in more detail with an immigration advice center – there are several Irish ones located in major cities throughout the U.S.
