In order to qualify for work in the USA, and to be eligable to obtain a VISA, you will need to take and pass the Commission of Graduates of Foreign Nursing Schools
exam (www.cgfns.org). Once you pass, and have a certificate, you may sit the NCLEX exam, in which ever state you wish to work. In order to obtain a VISA you will have to find a organisation or agency, that will sponsor you to the USA, this should be available within your home country, maybe on the internet. It will be difficult to find a USA sponsor, maybe. With both exams passed, you will stand a better chance. If I find any links to web pages, I will send them to you, hopes this helps, and hopeufully I have provided you with some new information.
