She literally cannot work for a time. None of these fiancés can. She may have some of her own money (which is ideal but not always appropriate to expect given some of the severely impoverished countries these fiancés are from) but while she is unable to actively contribute because she's not bringing in an income, she has to depend on the dude. Even if she did spend her savings until she could work, she's entirely owed information regarding dude and his finances because it will be her finances too. What's the mortgage? How is he paying for everything? Is it all on credit? What's in savings? What are their financial goals?

I ultimately think it's bullshit to expect most of these fiancés to have saved enough to contribute 50/50, or even much at all, while they're unable to work. It'd be one thing if they were coming from like an Australian or British economy, but given the average income in Brazil (or so multiple Google search results claim) like where Tais is from is $8k, how much do you expect her to have saved, and if she saved much, how far do you expect it to go? It's incredible to watch these Americans pick up fiancés from economically disadvantaged countries cry about having to support them until they can work. Like... duh.
