The article doesn't say, but apparently she got in line and became legal.
She does say she came here illegally, but "only for a short time", which seems to imply that she did become a naturalized citizen, since she's still here.
I don't have a problem with people that wnat to come here and become American citizens. The problem is the ones who come here and demand to be granted the privileges of citizenship, without any effort on their part or intent to shoulder the responsibilities of citizenship.
I read she was naturlized. I remember reading that when Cesar Millan applied for citizenship and was naturalized (he came here illegally as well) he had to pay thousands in fines in order to apply. I imagine Hayek did too.
My husband was naturlized and under normal circumstances (i.e. legally) it doesn’t cost very much. But if you declare you entered illegally, then apply, there are huge fines. I’ve read that there is a ban imposed (you have to return to your home country and wait a specified time) on those who entered illegally and then try to get citizenship, but somehow it must be waived for “celebrities.” Or maybe it’s a new law and these folks were naturalized before it took effect.
