When citizens or visa holders encounter a checkpoint, most are waived on after showing identification, but if an agent suspects the person is not lawfully in the country, the agent can detain the person until the agent’s investigation is satisfied.

The government has long had the power to set up such check points, but has recently expanded the number of permanent and ‘tactical’ check points and deployed them in areas they hadn’t before — such as near the Canadian border.
