Vietnam visa extension has been recently quite difficult as the Immigration of Vietnam has changed the policy on this. Limited permission is allowed for new issuance from 3 months onward for single or multiple entry. The longest one is 15 days to 1 month extension only. We may require you first the scan copies of your passport and current visa in order to inspect and check the actual thing with Immigration. Upon the agreement and price satisfaction, we will require your original passport for processing. Standard time is 5-7 working days. Urgent case can be up to 2-3 working days.
