My wife and I are traveling to SXM and AXA in the beginning of April. I just read that both SXM and AXA require your passport does not expire for at least 6 months before entering the islands. My wife has 2 passports, one from the US and the other UK. Her US passport will expire in late August (4 months). If she has a problem in either SXM or AXA with her US passport, can she use her UK passport to enter both SXM and AXA.
