According to a report of the World Tourism Organization and World Travel and Tourism Council, tourist visas are mainly regarded as a procedure to impose costs, including direct expenses for the visa fees and indirect charges, on tourists.
If the costs imposed by a country exceed a threshold, potential tourists do not want to make the trip to that county again or will choose an alternative destination.
This report also recommends that countries expand or facilitate the visa on arrival system, which can bring an additional six to 10 million international tourists to the ASEAN countries by 2016.
The increase in the number of visitors could bring $7-12 billion of additional revenue and create from 333,000 to 654,000 new jobs by 2016.
The report also pointed out that Vietnam can increase international arrivals by 8-18 percent if it implements the visa on arrival system.
