Can You Please Let Dual U.S. - Kuwaiti Citizens Know What To Do? Can The U.S. Embassy Issue Guidance For Such Dual Nationals?
When considering how to proceed in questions of dual nationality, you must decide the course of action which best suits your personal circumstances. The Embassy can, however, discuss with you the consequences of any actions you may take upon your U.S. citizenship. (KuwaitACS@state.gov). If you need to discuss the consequences for your Kuwaiti citizenship, you may wish to consider seeking advice from Kuwaiti authorities.

Such decisions should only be made after carefully considering the consequences.
