中美签证信息:CA-4

Central America-4 Border Control Agreement
The Central America-4 (CA-4) Border Control Agreement was a treaty signed in June 2006 between the Central American nations of El Salvador, Guatemala, Honduras and Nicaragua, establishing the free movement across borders between the four signatory states of its citizens without any restrictions or checks. Foreign nationals who enter one of the signatory countries can also travel to other signatory states without having to obtain additional permits or to undergo checks at border checkpoints. Similar to the Schengen Agreement in Europe, the CA-4 Agreement establishes a harmonised visa regime for foreign nationals travelling to the area.
