I highly recommend you get a 60 day tourist visa which you can extend for an additional 30 days when going for a retirement visa. I also, highly recommend you do not try to come on a one way ticket without having an exit ticket. I recommend getting a ticket to someplace like Singapore or Vietnam for your exit ticket. Either get one you can cancel or eat the $50-$75. When I presented my one way ticket the airline was going to deny my boarding until I showed them my exit ticket. DON’T chance it.
