Very simple, really....
Ive hurd so many stories its driving me crazy! I plan on going to DR March 18th (next month) and staying til..... I dont know whenever I get tired of being there (lol) It makes no sense for me to have to buy a ticket to come back when I dont HAVE TO come back.. Why do I have to come back? I didnt know it was illegal to stay in the DR if you were born in the US... I guess its a way of the US saying PLEASE DONT LEAVE US! WE NEED YOUR TAX MONEY! lmao.. I dont know but I swear if they ask me to buy a return ticket I am going to go crazy on them!
The origin of where you are leaving from,(country) and the airline you are flying with can vary. The US does not require a return ticket to be bought if you're US born. I fly AA all the time, one way, no problem. Sometimes I purchase a ticket to SJU when leaving and then to another island destination before returning to the US. All though the immigrations doesn't always look or ask for the return, it's required. You can't just fly into anywhere, any island and stay forever....legally that is......unless you of coarse have something of value to offer. Teacher, nurse, etc....and a show of income from your origin country. Again this varies between the different islands, and nationality.
If the US let anybody in from anywhere with no return, where do you think we would stand considering the number of illegal immigrants we have already, and the cost and problems they cause. Southern states are loaded with Cubans, Mexicans, throw in a few Haitians and Dominicans, Indians, Chinese, and what do you have? Just another war over jobs for starters. No diff here than in the DR. Dominicans don't want Haitians coming over with or with out work cards. There aren't enough jobs to go around as it is.
It's not a case of the US not wanting you to leave, the DR doesn't want you to stay. It's a due process.
Buy the round trip, throw away the return, and pay the fiddler when you leave if you ever have to. And think about getting a residency legally if you intend to stay.
