Question

how can a president make an agreement with the leader of a foreign country without involving congress

Answer 1

Answer: through an executive agreement.

An executive agreement is an agreement between two heads of state. In the United States, this would mean the President of the United States. An executive agreement is different from a treaty in that it does not need to be ratified by the legislature. Therefore, under the United States constitutional law, they are not treaties. While treaties are legally binding, executive agreements are politically binding.

Answer 2

Good Morning!
 
To make a deal without the participation of the legislature, the president can make an "executive agreement," which is not officially considered a treaty, since the latter requires an agreement approved by two-thirds of the Senate.
