Like accreditation, the American visa process involves both private and public agencies. The US has a federal government, meaning that the country is a combination of states. Our tradition, therefore, is to divide and distribute activities that would be centralized in other nations. This can be confusing to people from other nations.
If you want to work in the United States, you need a work visa. To get an H1-B visa for expert workers, you must have a corporate sponsor and show that your education is at least the equivalent of an American bachelor's degree. But not any American bachelor's degree.
A company that offers you a job will hire a law firm that specializes in this work. The law firm, in turn, will hire an agency that specializes in assessing educational credentials, such as the Foundation for International Services. The first step will be to look up your foreign degrees to see if they are respected around the world. US baccalaureates are four year degrees, so if you want to meet the standard, you need to present what in India, South Africa, or Commonwealth nations would be an honors degree.
If you have earned a degree from an American university, especially an online American degree, a US expert will be hired to review your credentials and determine equivalency. At this point, there will be one key question: does the US university from which you graduated have regional accreditation. Not just any accreditation, but regional accreditation.
Of course there are exceptions to these general rules. In some cases, but not all, work experience can be added to a 3 year foreign baccalaureate to make it the equivalent of a four year degree. The usual rule of thumb is three years of work experience for one year of education. The rules have been getting tighter, however.
So what is regional accreditation, and how does it differ from other accreditations?
