I'd add that I think it is important not to link marriages of convenience in a direct way with vulnerability. Certainly, some marriages of convenience could lead to vulnerability, but there's no interplay, if you will, between marriages of convenience and forced marriage, or those types of practices.
Like my colleagues at the table, I've worked in many different countries and marriages of convenience, whether individually organized or more organized scams, are pretty common in almost all our source countries. More specific cultural practices, which may lead to a higher incidence of things like forced marriages or polygamy and other types, are somewhat more culturally specific, although we have to be cautious about that too. Marriages of convenience were a big problem in Russia, Pakistan, India, and China when I served in all those countries, and certainly in South America and Latin America. It's a pretty broad problem, if you will.
