Actually your wrong, In Europe where I am from. The majority of countries in Western Europe grant birthright Citizenship. You are required to live in the country for 10 years until you are granted citizenship (To children born to non-citizen parents).

Now that being said, this bill will not pass the legislative branch. Why? Because of the U.S. Constitution, Obviously alot of the things in the U.S Constitution is outadated (However I dont think this amendment is), Americans have a very hard time disagreeing and even reapealing anything in the document, because "its our God Given right".

And From what I remember from my Government Courses. This bill will have to go throught the Legislature of all 50 states and 2/3 of the states must agree to this bill to repeal the 14th Amendment of the Constitution.
