H. R. 7701 is a rule that plans to stop people and businesses from helping build or fix bridges or tunnels between Russia and a place called Crimea. If they do, they might not be allowed to buy things or come to the U.S., unless what they're doing is to help people, and even then, the President can make exceptions if it's good for U.S. safety.

H. R. 7701 is like a rule that says people from other countries who help build, fix, or take care of roads or tunnels between Russia and a place called Crimea might get in trouble. The President can stop them from visiting or using money in the United States, but sometimes these rules can be ignored if it’s really important for America.

H.R. 7701 is a plan to stop people from helping Russia build bridges and tunnels to a place called Crimea by making it harder for them to visit the U.S. or use money from U.S. banks. It tries to prevent help from going to people who are not supposed to get it, unless it's for really important reasons like helping people in need.
