This is particularly so in the case where the marriage has been entered into to permit immigration. If you are caught, both partners could be subject to criminal penalties and in the case where the arrangment has facilitated immigration, deportation is likely. Deportation of naturalized or native born children is also possible in some cases. If your spouse is a new immigrant, you may in some cases become liable for their debts. As with all cases of deception, perpetration of this deception could leave you open to blackmail.
Discretion is of utmost importance.
What's Paramount Get a thorough understanding of the risks. If you have the option, it is preferable to marry someone you know well and know you can get along with rather than a stranger. If you are marrying to eliminate family pressures, then choose a partner who is a fellow citizen as opposed to a foreigner. This will reduce the costs associated with discovery of the arrangement. You must be confident that your chosen spouse is trustworthy and honest.
