The State Department has substantially increased charges for U.S. passports and visas for foreigners. Since July 13, the cost of a passport for an adult has gone up from $100 to $135, including a $25 administrative fee. Those under 16 now pay $105 with the fee, up from $85 previously.

Americans traveling by land or sea on trips to the non-U.S. parts of the Caribbean, Canada and Mexico have to pay more, too. The new scale for passport cards is $55 for an adult, up from $45; $40 for a minor, up from $35. Frequent travelers are also hit by a new charge of $82 to add more pages to an existing passport.

The State Department says the higher fees are based on a study of the true cost of providing these consular services, which the Department recovers through the collection of fees.
