In regards to immigration, there are different types of sponsors. In your case, it sounds like you are asking about a work sponsor. Basically, a work sponsor is a US employer that is willing to offer you a job and complete the necessary visa application on your behalf. However, it is important to note that receiving a job offer does not necessarily qualify you for a work visa. There are additional requirements that must be met in order to receive the visa.
If you would like additional information, we will need to set up a 30 or 60 minute consultation. If you are interested, please email me directly or call my office at 03-753-4000.
