If you are considering a fake, or sham, marriage as a means of getting U.S. lawful permanent residence (a green card), you must know that what you are planning is illegal.
A sham marriage is one that is entered into in order to get around the U.S. immigration laws.
The U.S. government will not normally follow a couple around or investigate their life beyond the required paperwork and the interviews it always conducts. But it has the power to do so if it sees grounds for suspicion.
Any individual who knowingly enters into a marriage for the purpose of evading any provision of the immigration laws shall be imprisoned for not more than 5 years, or fined not more than $250,000, or both (I.N.A. § 275(c); 8 U.S.C. § 1325(c)).
