What are the employment based visa categories?
For employment based petitions, each category is based on the type of employment you are accepting.The visa categories are usually based on skill and experience and industry.Each visa category has a certain number of visas available every year. If the U.S. government receives more applications than the number of visas available, then there is a backlog and a wait develops.
Here are the official definitions of each visa category. Please remember that this is a very confusing chart and is not that helpful. Each visa category will have its own technical requirements. Generally speaking the more highly skilled the position you are seeking is, the faster the visa number becomes available and the faster you will get through the process.
