Work Study Visa
If you are planning on going to the US for business or tourism purposes and will be staying for less than 90 days, you may be able to enter the country without a visa, under the Visa Waiver Programme.
If you are planning to travel to the US for study, you will need to apply for a non-immigrant visa. There are three types of student visa:
F-1 is the most common type of visa for those who wish to study in the US and is intended for those who will be attending an accredited US college or university.
M-1 is suitable for study at a non-academic trade or vocational institution.
J-1 sometimes referred to as an â€˜exchange visitor visaâ€™, is suitable for anyone studying on a pre-arranged programme or undertaking pre-arranged employment or research. This must be an officially approved programme that is sponsored by an educational or non-profit institution. (Embassy of the United States in the UK, 2009).
