This question concerns United States Border Patrol interior checkpoints. These checkpoints are located away from the external border, but within 100 miles of it, at which traffic may be stopped in order to check the immigration status of the occupants.
Noting 18 USC 1001 (see my related question for more information), I wonder how a dual citizen should react when faced with one of the usual questions asked by border patrol officers at these checkpoints:
Are you a US citizen?
- For a person who is a citizen of the United States and at least one other country, is it okay simply to answer yes?
- For a person who is a citizen of multiple countries, not including the United States, is it okay simply to answer no?
What country are you a citizen of?
- Is it necessary to disclose all countries of citizenship when responding to the second question? Does it matter if one of those countries is the US?
