From what I've read and heard, it affects tourist visas over 30 days and you have to get re-stamped every 30 days. Could drive away expats from VN like the Thai laws that are driving away expats in Thailand. Hopefully it doesn't affect most expats but could be a game changer for people looking to retire in VN.
