Sorry if this has been answered, I read through the 5 pages and didn't see it, though...
... does this pertain to infants?
If an infertile Lakota couple decides to adopt, say, a 10-month-old Japanese-American baby out of the foster system, does that mean the child doesn't get to be a member of the Lakota nation?
Also, what if they decide to use a surrogate mother?
I don't know anyone in any of these situations, I'm just curious.
If I were to adopt a Chinese baby, she'd get Swiss/US citizenships and all the benefits and responsibilities (taxes) associated with those nations. However, there'd definitely be some (not all) Swiss people who would think to themselves, "Yes, but she's not REALLY Swiss". It would be a personal thing, though, not a legal status issue.
