Applying for and completing an Employment Authorization Document, or an EAD, can require a large amount of paperwork that could be confusing to many foreigners, even for the most dedicated of applicants. Generally, an immigration lawyer is recommended to help applicants fill out their paperwork in a timely manner, review it for accuracy, and have it sent to the United States Citizenship and Immigration Services office for processing.
There are several different types of visas that a foreign national could apply for while temporarily staying in the United States. One of them is the H-1B visa, which is for specialized professionals. Another is the H-2A, which is for seasonal agricultural workers, and the H-3A, for seasonal workers in other fields. The final is the H-3 visa, which allows foreign nationals to receive work training or education that is not available in their home country.
The most commonly known visa is the green card, which is for permanent non-citizen residents. EB-1 visas are reserved for highly skilled researchers and scientists, international executives, and people of extraordinary ability. EB-2 visas are for professionals with a specialized skill-set, while EB-3 visas are for skilled and unskilled workers and professionals. Once a green card is issued, a foreigner can usually work in the U.S. indefinitely.
Work visas are a complicated part of the United States immigration system, but they are the most important aspect of what draws people to the United States in the first place. Because of this attraction, the immigration system requires an organized system that will allow people to come here and work while still vetting each person to make sure they have good intentions and are not hostile towards U.S. law or the American way of life.
