Those who are receptive should take heed, as their agents are recommending the use of a Visitor visa for relocation to Vietnam. I've received numerous inquiries in my inbox regarding the process of transitioning from a Visitor or student visa to a work visa. I've received direct communication from the Embassy of Nigeria in Hanoi, Vietnam, which I aim to share with the public and others planning to pursue this route.

hmmmm!!! those with no means to support themselves shouldn't go this route at all. Asia is not for the weak, as I always tell people asking me to help for Visa every time. If you don't plan to Japa to better country after Asia, you go learn.
