Business visa on arrival

You still have to get immigration to approve it, not your company.

For all kinds of VoA (tourist/business), you need to get a Letter of Approval from the Immigration dept.
Get in touch with any of those visa/travel agents. Tell them you already have a letter of invitation.
They will arrange your Letter of Approval (for B-visa on arrival) in 2/3 days.

At the airport, they will ask for that Letter of Approval NOT the letter from your company.

Just get your company to arrange a visa and go from there.

No, you wont get a TRC unless  you are Viet Kieu,married or have a work permit
