What was Washington’s foreign policy agenda?
Thanks

Washington's address argued for a careful foreign policy of friendly neutrality that would avoid creating implacable enemies or international friendships of dubious value, nor entangle the United States in foreign alliances.

The correct answer is
B. Enforcing immigration laws

Enforcing laws is a part of the executive branch and not of the congress which is the legislative branch. They can make laws but their enforcing goes down to the federal police or local state police departments or sheriffs and such people. The judicial branch decides whether such laws are constitutional.
