I live in d. 7 in Saigon and for many years had no issues receiving the occasional card or letter mailed to me from outside Vietnam. Beginning maybe a year ago, not sure exactly when, I no longer receive mail. I know this because I've been told of cards sent by friends that I never saw.
As far as I know, my residency status is up to date (red book). I'm curious if others have had this problem and how it was dealt with. I suspect some mail for me may be sitting in a box somewhere and I'd love to get it. My landlord is a Vietnamese woman and I'm thinking of asking her to inquire about it for me.
Thanks
