1. Get your credentials evaluated.
First and foremost step is to get your credentials evaluated. This is the foundational question that needs to be answered- what is your qualification for a certain immigration category and whether you meet the US equivalency or other are qualified for it or not. For example if you are going to get H1b work visa status, your education must be equivalent to US college degree (B.S. degree). If you did not get equivalency to B.S. degree, then instead of filing for work visa perhaps you will need to enroll as student to complete the number of units required to get B. S. degree. And a student visa will be required.

Similarly, if you are filing for L-1 category, your should have, at minimum, worked for the company overseas for at least one year out of last years and a certain business relationship must exist between the international company and US business-among other things. If you do not meet the criteria for L1, however, if you are a national of one the countries which has treaty with the U. S., you might qualify for E-1 visa.
