What if I wish to extend my visit while I'm in Vietnam?
No problem, you can always extend your visit in Vietnam!
You are normally given a one month single entry travel visa, which lasts 30 days. If you plan on extending You should need to make your decision at least 7 days before your visa is expired as it normally takes about 2 working days to get your visa extended. Extensions are usually for another one month period. For longer stay visas or extensions, it may take about 7 to 15 days to get.
There are also 3 month tourist visas available at a reasonable cost when you enter Vietnam. Ask your visa provider about this option before coming to Vietnam when you are applying for your pre-approved entry visa letter. Then you do not have to worry about extending your visa when you here.
