I traveled to the United States, and the visa for a family of four with two children has passed. I brought three quilts and some children.

No, the quilt and clothes are packed in the suitcase, and people won't let you open them. When you go through the customs, you may be asked if you have brought food, seeds and other items, but you just didn't have them all the way.

If the random inspection finds that one in ten thousand cases is unpacked, then your quilt clothes have nothing to doubt. Just tell them the itinerary and show them the return ticket. No problem, don't worry ~
