I was born in Ohio to two U.S. citizen parents, who were also born on U.S. soil, and I am a citizen under the 14th Amendment of the U.S. Constitution. Congress cannot revoke my citizenship without my consent merely by passing legislation.
Actually, the 14th has no bearing on your citizenship - as pointed out in M v. H.
You are a true natural born Citizen. And that form of citizenship pre-dates the 14th. And it even pre-dates Congress. There had to be citizens before there was a Congress. Of course at the time the Citizens (capital C) were Citizens of states. And were still Citizens of states after the formation of the nation and Congress. Congress was charted (via the Constitution) to create UNIFORM naturalization for ALL the states since each had varying forms of naturalization and were allowed to do so under the original Articles of Confederation.
Natural born citizens (born to citizens parents in country) need no or amendment to be citizens.
