The purpose of this legislation is to strengthen immigration laws by making it clear that non-citizens who violate certain hunting and fishing laws can be denied entry into the United States and can also be deported if they are already living in the country. This law aims to protect wildlife and enforce regulations related to hunting and fishing. The key provisions of the law state that any non-citizen who has been convicted of, admits to committing, or has committed acts that violate state or federal hunting or fishing laws will be considered inadmissible.
