Refugees: People who have been forced to flee their home country due to war, persecution, torture or imprisonment for their beliefs. They come to the United States through the U.S. Department of State Refugee Resettlement Program after passing immigration interviews, background checks and medical exams. Often they have spent years in refugee camps before having the opportunity to apply for resettlement.
Asylees: Like refugees, they have fled their home country due to war, persecution, torture or imprisonment for their beliefs. The difference is that an asylee makes it to the United States, on his own, and once here, applies for asylum. The process can take many years. Asylees may be granted asylum by an immigration officer or by an immigration judge after proving they have a credible fear of what would happen if returned to their home country. They also undergo background checks.
Immigrants: Encompass a variety of reasons and ways of coming to the United States. Some are sponsored by relatives, some are sponsored by employers, and some are here based upon their talents, education or skills. Some come through the system, some do not. Most work hard to support their families and to make a better life for their children, just like most native-born Americans and our immigrant ancestors.
Internationals: People who are living in the United States for a specific period of time but intend to return to their home country. They often come through an employer or business, or to study, or to visit relatives. Their stay can be just a few days or can be several years. While here, they learn about the U.S., its people and culture.
