My girlfriend and I will go to Laos for one year. She will have work there. We are not married and, anyway, the situation doesn't allow anything but a tourist visa for me because I will continue to work for a French business, telecommuting. I will maintain a tourist legal status.
Laos issues one month tourist visas on arrival. You can renew them twice (up to three months) at the immigration office if I got the correct information. After that, you have to exit the country and enter again to get a fresh visa on arrival, that will be valid for one month, renewable two times.
People on forums told us that you can get infinite visa renewals at the border, but that seems odd to me. They said:
you can go in, and out, and in, and each time you got a fresh visa on arrival from the local immigration office.
I can't get an official confirmation for this statement. What are the rules? Is there some under the hood rules?
