Domestic flights without any unaccompanied-minor procedures. Some airlines permit this for kids as young as 12. When a child has reached this minimum age for traveling alone without unaccompanied-minor procedures, the airline does not require evidence of parental permission to travel alone.
Ing to USCIS data from 2023, the average processing time for Form I-131 (Application for Travel Document) varies between 3 to 7 months, depending on the service center handling the case and the specific category (e.g., refugee travel document, re-entry permit).
You have 2 options for filing your Form I-131 application with USCIS: Online (only available for certain application types); or. By mail (on paper).
The letter should say: "I acknowledge that my child is traveling outside the country with the name of the adult with my permission." A parent who frequently crosses the border by land with a minor should always carry a letter of permission from the other parent.
The travel document usually arrives within 150 days (sometimes longer) after submitting your application. You can't leave the country until you have your approved travel document in hand, so you should expect to spend the 3–5 months after submitting your green card application in the United States.
A letter of consent, preferably in English and notarized, from the other parent or signed by both custodial parents. The letter should say: "I acknowledge that my child is traveling outside the country with the name of the adult with my permission."
In the USA, though, unless there's a court order requiring permission from both parents, a child may travel (even to overseas) with either parent/guardian without showing proof of permission from the other parent.
Typically, minors under the age of 18 do not have to present identification for domestic U.S. travel. Airlines will accept identification from the responsible adult on behalf of the minor(s). For international travel, minors under the age of 18 must present the same travel documents as the adult.
A consent letter is recommended for all cross-border travel, even for a day trip, if the child will be travelling alone, with only one parent, with friends or relatives or with a youth group.
