In this context of legal immigration, the point here isn't about sovereignty. It's simply documenting one persons experience - I don't see it as a call for open borders. Also, does the US recognize a country's sovereignty when it conducts its foreign affairs? It constantly meddles in the internal affairs of other countries, not to mention the countless military interventions over the years.

We are talking about a less than 2 decade time horizon for citizenship for immigrants who are propping up your welfare state of birthright citizens with 100K$+ payments in income tax every year.
