Her name(Elena Matsuk) is submitted to United States Immigration & Naturalization services & Canadian government & European Union watch list.  Whoever shall try to sponsor her in future will definitely have a hard time clearing her name for visa purposes.
North America & EU is out of the question. 
Type of marriage fraud that occurs when a person deliberately marries for the sole purpose of
attaining an objective, dissolving it once it has been gained. Occasionally, foreign nationals may
engage in marriage fraud with U.S. citizens for the sole purpose of gaining citizenship for themselves,
an act which is illegal under U.S. law. In order for foreign nationals to acquire U.S. citizenship
through marriage, they must first meet certain conditions which vary based on a number of factors,
including where the foreign national currently resides and whether he or she is engaged or already
married to the U.S. citizen. As with any other foreign national seeking U.S. citizenship, they must
apply for citizenship with the U.S. Citizenship and Immigration Services (USCIS), which, as part of
the application review process, refers the applicant's case to the Immigration and Customs Enforcement
(ICE) division of the United States Department of Homeland Security (DHS). ICE's Identity and Benefit
Fraud Unit (IBFU) investigates the prospective citizen and, among other things, determines the
legitimacy of his or her application. If ICE believes the applicant is attempting to engage in
marriage fraud or some other type of benefit fraud, USCIS may deny the application. Furthermore,
the applicant and/or associated parties might be subject to prosecution on the part of ICE. If you
suspect someone of engaging or attempting to engage in marriage fraud, you may report it by calling:
1.866.DHS.2ICE (1.866.347.2423) with their full name & what they did.
