You should look into DTV visa if you have the funds, 5 years validity and gives you 180 days each entry can be extended another 180 before you have to do a border run. Working is difficult to find a company that want to hire a farrang since alot of red tape but possible.
correct no report if you enter on visa extempt or tourist visa. Since you go out the country before the 90 days is up, but when you return don't forget where you live have to send new report at you staying there
