Moldova Passport and Visas Information
Citizens of US, EU, CIS countries, Canada, Norway, Switzerland, Japan do not need a visa to enter Moldova and can stay in the country for up to 90 days within a six month period without registration. Citizens of other countries must either obtain visa in the nearest Moldovan embassy or alternatively could obtain visa on arrival in Chisinau airport and on some land border crossings provided that officially endorsed invitation letter from Moldova is obtained beforehand.
If, being a motivated person, you are coming into Moldova via Ukraine , be careful about crossing Transnistria. Buses from Odessa go through Tiraspol. Transnistria is an unrecognised "state" between Moldova and Ukraine, which broke off from the country after a war in 1992. Foreign travellers have in the past experienced problems, although as of this year (2010) there are few issues for Westerners in crossing Transnistrian borders by bus. There is, however, a small chance that foreign tourists may be asked to pay bribes, although the buses which travel between Moldova, Transnistria and Ukraine usually handle negotiations at the border well, collecting passports and negotiating with Transnistrian authorities. Also, there is no Moldovan border check between Transnistria and Moldova as Moldova does not recognise Transnistria as a state, so you might have some explaining to do when you try and leave Moldova without an entrance stamp.
