I'd like citizenship swapping services. Some people just don't wanna stay stuck to their country of birth, especially if renouncing that citizenship is literally impossible (I'm Moroccan, and according to Moroccan law I'll stay that way to my own detriment, even if I get another citizenship which thankfully is possible).
I bring this up regularly. Trading a doctor for a doctor seems like a fair enough trade & many folks want mobility. The irony of “if you don’t like it here, then leave” being met with your & other nations making it exceedingly difficult to do that. I know several folks would love to have my US passport but where I am at, I would get a lot more value & ease in having a local passport form entry to nearby countries, to visa woes + residency, to opening accounts (dealing with the IRS+SEC means many, many places refuse service), dual pricing, & actually getting some semblence of integration.
