In that case one obtains H-1B visas – that can be obtained in less than 30 days. But be aware, such visas are valuable just for the period from 1 up to 3 years. And is valuable just in the case you still work for a person that offered you a job. Most common areas of interest are: medicine, nurses, journalists, researchers, scientists, information technology professionals and accountants.
In regard with education the USA is generous. Between most common visas are J-1 visas that are offered in the case of exchange visitors. Means that from particular areas of their interests, mainly medicine, they allow exchange of visitors and thus a worker is able to study, participate on some project and work in the USA for a period of time 2 years.
There is built mechanism in general standards recognized by nations. To judge the USA one must have all information. The USA is fully within this standard, but as a “great power” it falls behind in some cases. The USA is very strict concerning the flow of foreigners to their country. It accepted just the parts of general standards covering areas of: business and education. In other cases Americans are rather strict and no one would ask why after September 2001.
 2, this short article will answer some of the most frequently asked questions and answers about the immigration law of the USA. One of the most asked questions for us aliens remains the information about “what if I risked it and remained in USA illegally?” They have simple process with aliens that break immigration law. If one stays in US for more than 6 month illegally one is thus barred from the USA for the period of time – 3 years. If illegal period spent in the USA is more than 1 year in that case a person is barred for more than 10 years. Here it can be clearly seen why immigration law is in the binding form. It provides clear rules, steps that are divided into groups and that must be strictly followed. / that is according to me right. /
The second question is usually what categories of temporary visas are in the USA. First there is H-1B Specialty Occupations that I have written about before. Then there is J-1 visas Exchange visitors, concerns mainly various educational institutions and organizations. This is important mainly for medical training and this visa holder complies a two year foreign residency. As I have mentioned above then there are Treaty Traders E-1 and Treaty Investors E-2, for investors and businessmen that are coming to the USA.
