birthright citizenship

基本解释

If birthright citizenship were abolished, these children would not be U.S. citizens, at least not automatically as at present.
如果出生地國籍主義被廢除，這些子女就不會是美國公民，至少他們不會像現在那樣自動成爲美國公民。
Some conservative libertarians are arguing that birthright citizenship is bad for the country—and some progressive libertarians are arguing that it is bad for immigrants.
一些保守的自由主義者認爲出生公民權對這個國家有害，而有些自由主義改革派則認爲出生公民權對移民有害。
But closing the loophole that encourages foreigners to come to the United States solely to make their future children U. S. citizens would not address the larger question of birthright citizenship.
