There are a variety of misconceptions about immigration law. Yes, it is difficult to become a permanent resident, but, probably the biggest misconception is that a foreigner must be able to speak and write in the English language. This is false – an alien can become a permanent resident without the ability to speak or write in English, though it does make it difficult to pass a citizenship test if an immigrant is trying to be naturalized.
Another misconception is that legal immigrants, who are in the country on a visa, can be deported for minor legal infractions, such as traffic tickets or DWIs. This, again is untrue, except in extreme circumstances.
Further, you do not have to be married to bring a child into the United States legally. Regardless of your marital status, children are eligible to relocate to the United States under a Family Visa petition.
Finally, the biggest misconception is the belief that once you come into the United States illegally, you cannot then become a legal immigrant. Even if you are an illegal alien, you can still petition the government for a visa, green card, or a temporary worker visa.
