Children from the Karen tribe point to American destinations on a display that promotes immigration to the U.S. at Mae La Oon refugee camp in Thailand. In 2006, the UNHCR identified Karen refugees as a group requiring particular protection, Canada responded by agreeing to resettle over 3,500 of them over three years, making it the third largest recipient with USA being first and Australia second.
