Entering or even attempting to enter illegally, is a criminal offense. https://www.law.cornell.edu/uscode/text/8/1325 https://www.law.cornell.edu/uscode/text/8/1325 "... Any alien who (1) enters or attempts to enter the United States at any time or place other than as designated by immigration officers, or (2) eludes examination or inspection by immigration officers, or (3) attempts to enter or obtains entry to the United States by a willfully false or misleading representation or the willful concealment of a material fact, shall, for the first commission of any such offense, be fined under title 18 or imprisoned not more than 6 months, or both, and, for a subsequent commission of any such offense, be fined under title 18, or imprisoned not more than 2 years, or both. ..." I would also suspect, that knowingly demanding/putting ones children into position to protect parent's illegal activities, should be illegal. Although, admittedly, I do no know by which statue.
