The online visa application does not allow to ente the information of those seaports and we can't either obtain a visa upon arrival, because according to the information in this page it is only granted in the airports; no Vietnam Embassy in Puerto Rico either.
Please advise us as how we can obtain a single tourist visa.
Dear Hilda del Toro Lugo,
We can not support visa for Phu My seaport , Please apply visa with your cruise ship
We apologize for any inconvenience this may cause
