i think it’s possibly illegal to do green card marriages
Indeed it is illegal to marry expressly for the purpose of facilitating immigration. Here's a summary from
a legal site:
Is a Marriage of Convenience Legal?
Marriages that are entered into for reasons other than love are generally legally so long as the individuals follow all the marriage requirements for a legal marriage, such as having a valid marriage license and being of age to marry. Certainly, people marry for reasons other than for love. However, when two people marry with the intent to commit fraud, such as marrying in order for one person to gain U.S. citizenship, it is illegal.
What are the Consequences of a Sham Marriage?
Sham marriages carry severe penalties with them. For example, if the sham marriage is based on immigration fraud, penalties can include:
A $250,000 fine;
Permanent removal out of the United States (i.e. deportation);
Loss of current immigration status;
Lifetime ban on obtaining U.S. Citizenship;
Annulment of marriage; and/or
Possible conviction of a federal crime.
If one person created a sham marriage (i.e., one party intentionally deceived the other), the guilty party may have to pay retribution. This is typical if the arrangement resulted in losses to the innocent party. Often the marriage will be legally annulled. Serious offenses may be recorded on one’s criminal record.
So how does U.S. Citizenship and Immigration Services (USCIS, who evaluates marriages inside the US) know if your marriage is "sham" or not? Well, one way is that they interview you and your spouse-to-be to determine if it seems like you are in a real relationship. Here's
one description of this:
"At the interview, questions will typically focus on the history of your relationship, your day-to-day activities as a married couple, and your future plans together. The interview is also an opportunity for you to present extra evidence to prove the authenticity of your marriage.
If the agents suspect your planned marriage is one of "convenience", then you may be subject to the so-called "Stokes Interview" where they interview you and your intended separately (like interrogating the suspects in a crime to see if their stories match). Some reasons for this are:
In general, there are at least three reasons that a couple would get the extra scrutiny of a Stokes interview:
"USCIS has identified general “red flags” that suggest the possibility of a fraudulent marriage (for example: a large age gap between the spouses, a very short marriage, very different cultural backgrounds, or different addresses showing up for the spouses online).
USCIS has uncovered potentially adverse evidence about the marriage based on an FDNS investigation.
During the course of a regular interview, the USCIS officer can choose to switch to a Stokes interview format if new information has come up that they want to explore more."
The FDNS is The Fraud Detection and National Security Directorate (FDNS) of the U.S. Citizenship and Immigration Services (USCIS). They also conduct surprise site visits (come to the home of the married couple) to investigate the true nature of the relationship.
Here's a page on this. It's pretty scary!
And, if you intend to terminate the marriage after getting your green card, you have to be very careful, as that is a red flag. The green card you get from marrying a citizen is "conditional" for the first 2 years, then you apply for a 10-year green card. If your marriage ends before that time, you will have to jump through a zillion more hoops to prove the marriage was legit to begin with. There's also complicated financial implications: the citizen spouse is legally responsible for supporting the immigrant spouse for 10 years after the spouse gets their green card. This is so if the citizen dumps the immigrant, the immigrant won't be dependent on government support (welfare). The governments has put a lot of thought into making this path to citizenship as difficult as they can!
