Hundreds of Burmese refugees living in Thailand are being considered for resettlement in the United States.
The International Organization for Migration says it has begun medical pre-screening for at least 1,800 Burmese refugees.
The refugees currently resident in Thai urban neighborhoods. Last year, the Thai government said it would begin relocating such refugees to camps near the Burmese border. Those relocations have not taken place.
International officials say they expect the first Burmese refugees to be resettled to the United States as early as late May or June.
