Wondering if we were to surrender our children's US passports (or whatever correct terminology is) officially...so they aren't liable to pay US tax when older. I know as an adult if this is done there can be a very hefty financial cost to this...is this the case if we do it now for the children? (We don't live in US now, but do live in a country without a reciprocal agreement so have to pay US tax on top of local tax).
Totally taken in to consideration that this would mean they couldn't automatically live in US if we did this!
If I've not used correct tax/immigration terminology then apologies!
