1 is usually never preferred because the country is complete shit (or else why would they want to leave in the first place?)
If it's always such shit, then why would anyone walk around waving the flag of their home country in a thumbing thier nose at the host country way? What number is that process on your list?
It's funny to me, in this conversation, suddenly the USA is the greatest fucking nation on earth, bar none. The air of American superiority rivals that of the most nationalist nationalist. Streets are not only paved with gold, they are studded with diamonds on top of it.
In the very next thread comparing the US to- wherever, it's just a big shithole with no jobs, no future, everything sucks... but in this discussion? HOW could anyone not see leaving their kids behind in this great great greater than great great most awesome place as forehead-slapping OF COURSE!?
Sorry, people leaving thier kid in a foreign country is a douchebag move, I don't care of the streets really were paved in gold and studded with diamonds and you hated your "rotten" home country so much you didn't fly it's flag in everyone's face.
How about people expend some of the effort and energy to make their "rotten" home countries better places first before demanding to change nations they just snuck into?
