how to check if your passport is expired
Check Travel State.gov for the expiration date of your passport by entering the year your passport was issued and how old you were at the time of issue. After entering these numbers, you can determine the exact expiration date of your passport. Check the passport laws for the country you intend to visit. Some countries will not allow you to visit within six months of your passport expiration date. Brazil, Singapore, Ecuador, Indonesia, Romania, Israel, Paraguay and Malaysia will not allow passports within six months of expiring in their countries.
