“Additionally, we will encourage more airports to become pre-clearance locations,” said Homeland Security Secretary John Kelly. “This is not only enhances security, it also increases convenience by allowing international travelers to go to customs and border security screening before boarding flights to the United States.”

Kelly said airlines and airports that choose not to cooperate or are slow to adopt could be subject to other restrictions.
