What is a green card?
A green card, or permanent resident card, is a document that allows foreign nationals to permanently reside inside the United States of America.
What documents do green card holders require to travel outside of the US?
You have to present either the passport of your citizenship or obtain a refugee travel document. In addition to this, you may have to obtain a travel visa, but this depends on the entry requirements of the country you're visiting.
