He says that to enter the country indefinitely, the most optimal it´s being already in the country. Then arrange the papers.
I think the legal way is the best way. for example, if eventually I was in Sweden, and I decide I want to stay, I have to marry someone, go back to my country at the Swedish Embassy in Chile, show the documentation that my husband is in Sweden and apply for residency in this way. they can tell me "no" and I lose the money from applications.
which sucks for those who are not interested in marriage.
