I've been lucky not to have undergone in-depth screening exiting US Customs during the few international trips I've made, except for one Agricultural check a while back.

I've always completed the Customs declaration form so that I have the least likelihood of a further screening. I mark NOs on each item, even though it might not be true.

What worries me most usually is the food question. Are you bringing fruits, plants, food, and insects? I usually indicate NO, even if I am traveling with food (usually pastries and snacks).

What type of further questioning or examination will they subject me to if I indicate YES, I am bringing food? If I indiciate NO, and they find out I was not being truthful, will there be a fine levied against me?

Will I definitely get sent to another screening if I indicate YES, I am bringing meat products into the US?
