Moving. It’s something I’ve just done, though not in Vietnam. I’ve done it before, however, and there are a few things to consider, legally, that might affect your relocation efforts.
First, land, or property. In Vietnam you can’t own land as a foreigner, or even condominiums. You can only lease a condominium or house in a development for fifty years. However, you could obtain Vietnamese citizenship after five years of residency and language training and tax paying and then own land. But that’s the hard way. I’m sure that eventually this restrictive area will be deregulated further and Vietnam will host a condominium law similar to Thailand or Cambodia.
Rent tax. There is a tax, and depending on who you rent from, you may have to pay this in addition to the rent.
Registration of living. You are required to register with the police for every night you stay in a place in Vietnam. If you move into a new apartment or a new hotel you will have to register with the police and let them know that you are where you are. This involves a copy of your passport. Usually the landlord will handle this, but make sure it happens, otherwise there may be dire consequences.
Work permit. If you’re working in Vietnam, then you need to have a work permit. This can be handled through your employer but is necessary if you wish to continue working in Vietnam. Some of Vietnam’s requirements for obtaining a work permit are draconian, so beware.
Otherwise, you’ll also run into shipping issues. You can’t ship household goods into Vietnam without a work permit. And you can’t get a work permit until you’ve started working. It’s a catch-22, unfortunately, but you’ll have to work your way around it. So there are a few hints about moving in Vietnam. Make sure you stay on top of the law, rather than the law staying on top of you.
