If you believe the way to further your career or earning potential is to come to the United States, then it is best to do things by the book.
There are plenty of people working illegally in the U.S., but it is a stressful way to exist. Not only do you have to contend with the fear of the immigration authorities catching you, but you have to deal with unscrupulous employers who take advantage of your illegal status. They may pay you below the legal wage and deny you other benefits that legal workers enjoy.
Not everyone has the same opportunities
Things will be much simpler if you are a close family member of a U.S. citizen. If you are married to one, the child of one or the parents of one, they may be able to help you join them and work legally on a family visa.
Your status may allow you to work
If you have Temporary Protected Status, you should be able to work temporarily. This is extended to citizens of certain countries with major economic or safety problems, such as Venezuela, Somalia and Yemen.
Sometimes it depends on your skills
If you have particular talents, skills or experience, it can be easier to get a visa than if you do a job that people within the country could easily fill. For instance, if you are a university professor with specialist knowledge of Russian economics, your application may be fast-tracked in a way that won’t happen if you drive a bus for a living.
That said, there are certainly opportunities for people to come and drive buses and fill other essential roles, especially if they can get a job offer first. Talking to someone with experience helping others gain employment visas is an excellent first step to take.
