Common Visa

Thailand and Cambodia signed an agreement that the foreigner who got either visa can enter both countries. This is the aim for the promotion of the tourist industry. After each country amends the domestic law, it is said the "Common Visa" is issued. The leaders of the two nations said that it is possible for Vietnam, Laos and Myanmar to take part in the "Common Visa". I think this agreement is useful for foreigner and these countries. So, I want to carry out this system in many countries.
