VISA query urgent

Dear Sir/Madame

I am travelling with vietnamese familiy in Vietnam to visit vietnamese familiy there.
My girlfriend, which is vietnamese and her familiy, they all get their visa already. As I wanted to ask for a Visa in Bern (Switzerland) it was denied because of nationality of Turkey.
As we all have booked our trip to Vietnam already and everything is already payed, I would like to ask you if there is anything else I can do to get a Vietnam Visa.

Last year I was in Vietnam and I get a Visa. I was so excited about this beautiful country so we decided to make holiday againg in Vietnam with th whole family this year.

Thank you for your replay and have a good day!

Kind regards,
Tayfun Misir
