My husband has the 24-month extension letter, is a Philippine passport holder, and we'll be traveling to Manila this May.
While in Manila, we'll be making a side trip to Saipan (Northern Marianas) and Guam for a few days each.
Since both are US territories, his entrance should be treated as re-entering the US but I worry if the immigration officers over there will know what the extension letter is and if they'll give him a hard time.
Does anyone here have experience going through those territories and know if there will be any problems?
