Candidate Requirements for H1-B Visa:
Candidate must have secured job offer from a US source.
In order to get an H1B visa you will need the equivalent of a US college or university degree in a relevant subject.
If you have been educated outside the US, this requirement can often be met by:
EITHER - A non-US and/or only partly relevant degree, followed by three or more years work experience.
OR – Twelve years of high-level work experience.
NB If you wish to practice a profession such as law, medicine, or accountancy, etc, you will also need to obtain the relevant State or Federal licence to practice in the place of intended employment.
