This might be one of those things that depends on the authorities on the country in question. I know here in Argentina it's enough to cross to Uruguay and go back and your tourist visa gets renewed. A lot of expats do this to avoid doing the paperwork for residency though it's very easy to do. Those that stay long term do tend to get residency and eventually citizenship as well since it's very easy to do though.

I have no idea how it works on other countries but I suppose it depends on the authorities. I think for Europe you get a single tourist visa for the entire Schengen Area.

And yes, I should add, in our case it's irrelevant if you arrived/left by plane or boat, you just need to show your passport stamped proving that you entered and left the country within the allotted visa period.

Also:
I suppose it depends on the US authorities, if you are travelling to a sketchy country they might look at you funny when you go back home, say you bought a two way plane ticket to Costa Rica and decided to go to Cuba in the middle of your trip, that may raise suspicions.

So it's hard to give you advice without knowing the destination.

so you can just cross the physical border of the country turn 360 degrees and go right back inside and you have another 30 days or whatever without any paperwork?

>>2732839
Yup. At least a few years ago it was just that easy.
I mean they do a background check every time you cross the border, but still, some countries are more permissive than others.

I should add, this applies to Americans, Euros, Canadians, Aussies, most Latin American countries, some Asian countries like Japan, SK and a few other countries that get automatic tourist visa not for any country. If you need paperwork for a visa you are gonna have to do it all over again.

Also you need residency for many things like opening a bank account or certain doctor appointments so it's not a lifehack I would recommend if you are staying long term.

But for OPs case yeah it's doable.

you can leave by any way you want.

>>2732830
As others have noted, you can generally leave however you want, and you can almost always go to a third country rather than directly back to the US, assuming you can legally access the third country. There are a few exceptions, but the main thing any country you visit is likely to care about is that you don’t stay longer than you’re entitled to, either by the terms of a visa or a visa-exemption agreement. So for the aforementioned Schengen Area, for example, you’re allowed to stay for up to 90 days visa-free, but when those 90 days are up, you’re expected to be out for a full 90 days before coming back. As long as you don’t violate this by staying too long or coming back too soon, they don’t care how you leave or where you go when you do.

Countries that ask for return flight information on arrival are just checking that you’re leaving within the prescribed period, not that you’re on your specific departing flight, 99 times out of 100.

It's usually airlines who check and enforce onward travel requirements. Immigration officials only care that you leave the country before your stay expires. I'd be more concerned with the entry requirements of the next country, particularly if it requires a visa. I bought a $10 rental ticket for my trip to Thailand, but didn't need to present it. People use those fake ticket services all the time with no issues.

They don’t care once you’re inside the country what the details of your return ticket were. You can even try using a fake return ticket and then the worst that happens is they force you to buy a return ticket on the spot
