I would be surprised if the paperwork you received did not address this somewhere. If not, call and ask. When I went to the Philippines, we went to the Provo MTC, so there was no similar confusion. Search your paperwork for the info, or a number to call.
Congrats on the call, I had a friend go to Davao and he loved it there. The Philippines is awesome (even if uncomfortably hot and humid).
Tis easy enough to be pleasant, When life flows along like a song; But the man worth while is the one who will smile when everything goes dead wrong. Ella Wheeler Wilcox
God does notice us, and he watches over us. But it is usually through another person that he meets our needs. Therefore, it is vital that we serve each other. Spencer W. Kimball
