How to get passport & Exit-reentry visa

[K430751@kepco.co.jp]

Chao cac bac,

We are now preparing to hold "giam cuoi" in December in HCMC.  Then we 
are now plannng to "di Nhat ban nhau" just after giam cuoi.  (It is too 
cold for her, may be.  But.......Mmmmm.)

But as we are not familiar with how to get passport and exit-reentry 
visa for my dearest.

We have now completed marriage procedures already and have certification.

Please let us know how to get passport & visa in HCMC.  (I already know 
how to arrange entry visa to Japan, because I had been arranged so many 
person to enter ON BUSINESS...)

Thank you
Tsuchikawa
