It is generally considered that while dual nationals are in the country of which they are citizens that country has a predominant claim on their allegiance. You are bound to obey the Policies of Philippine Laws while you are on your Mother Country. Meaning, you are more of a Filipino than American when your foot is in Philippine Soil. Try to consult this with the US Embassy first; do not do fast decisions here, kindly wait for your "Recognition of Divorce Abroad" result. As with Americans who possess only U.S. citizenship, dual national U.S. citizens owe allegiance to the United States and are obliged to obey its laws and regulations. Such persons usually have certain obligations to the other country as well. Although failure to fulfill such obligations may have no adverse effect on dual nationals while in the United States because the other country would have few means to force compliance under those circumstances, dual nationals might be forced to comply with those obligations or pay a penalty if they go to the country of their other citizenship. In cases where dual nationals encounter difficulty in a foreign country of which they are citizens, the ability of U.S. Consular Officers to provide assistance may be quite limited since many foreign countries may not recognize a dual national's claim to U.S. citizenship.
