This bill is about making rules to stop people from helping Iran sell oil and related goods to support bad activities like building dangerous weapons. It says that certain people might not be allowed to enter the U.S. and can have their money here blocked if they break the rules.

H.R. 1422 wants to stop people and companies from helping Iran sell oil and gas by making new rules that could block their money and stop them from getting U.S. visas. It also sets up a group to help everyone work together to make these rules stronger, except there are some rules to help people if they need food or medicine.
