I don't understand your question.
Marriage fraud to violate Immigration law is illegal and a felony. It is illegal to marry someone to make them legal.
It is not illegal to marry an illegal immigrant because you love them. It is not illegal for you to immigrate your illegal spouse...assuming that the marriage is legitimate.
It is illegal to mar them.
Deportation.
The immigrant's status might come into play. Legal? Undocumented (illegal)?
It doesn't because the illegal immigrant has been before the economy was bad. In fact many Mexicans were called from Mexico during WW2 to work in factories >
yes because you are housing an illegal immigrant
an alien
Yes, he will be able to get his greencard faster, but it may still be a long, grueling process. It depends on why he is illegal. If he is illegal because he snuck into the country, it will be very difficult for him to get a greencard.
The illegal immigrant will be deported when caught.
Your question reveals an unconscious bias. You said,= "How can a US citizen sponsor an illegal immigrant...." = If you "sponsor" them, they are not an "illegal immigrant." Careful, the way your question is phrased says a lot about you. The very term "illegal immigrant" is insulting to ....migrant workers, especially. Mexican citizens surely don't like the phrase and, by the way, Superman was apparently an "illegal immigrant" and you SURELY wouldn't want to insult HIM.
One illegal immigrant is able to marry another in the United States. However, it does not change the immigration status and actually could lead to deportation because of the paperwork filed with the state.
Yes a illegal immigrant can move back to Mexico by car because if they are illegal immigrant can. And they are not be force to go back to Mexico but it was their decision on going back by car. Even though they bought the car in the U.S they can still take the car with them because they bought it. Plus the illegal immigrants can stay in the U.S so they have to go.
An illegal immigrant can go to a hospital for emergency medicine.
The guy who said that if you're an illegal immigrant with a misdemeanor, you get deported is wrong. It depends on which state you live in. Democratic states are more likely to let an illegal immigrant go simply by paying the bail charges. In a republican state, the illegal immigrant may not be so lucky (I don't know the answer for a republican state).
