What nuances and rules you need to know when obtaining a visa and a residence permit
First of all, we get a pass to the country. It is quite simple. The visa stamp is placed directly at the airport. And for many countries it is free. For a longer stay, you should open a work visa for 3 months with the possibility of extension. This procedure can be done in the Department of Immigration of Vietnam.
But with this question it turns out somewhat different. It is necessary to submit an application that is individually considered and confirmed by the president. It is issued mainly to political immigrants. You can bypass this procedure, for example, having married a citizen of Vietnam. This does not give the right to obtain citizenship, but a residence permit in your pocket.
