🚨 1. Federal Offenses (U.S.)
If a minor (under 18) travels internationally for the purpose of engaging in sexual activity, it can trigger multiple federal crimes, even if the travel was “consensual” or parental-approved.
Relevant U.S. laws include:
18 U.S.C. § 2423(a) — Transportation of minors with intent to engage in criminal sexual activity.
It’s a federal felony to knowingly transport a minor (under 18) across international borders with intent to engage in any sexual activity that would be illegal in the U.S. or abroad.
Punishment: 10 years to life in prison.
18 U.S.C. § 2423(b) — Travel with intent to engage in illicit sexual conduct.
Even if the adult only “arranges” or “encourages” the travel, this law can apply.
Punishment: up to 30 years in prison.
18 U.S.C. § 2423(d) — Arranging for or facilitating travel of a minor for illicit sexual conduct.
Anyone who aids or encourages the travel (including parents who approve it) can be prosecuted.
⚖️ 2. Parental Liability
If the parents knowingly approve or assist a minor in moving abroad to be with an adult for a romantic or sexual relationship, they could also face:
Federal charges under 18 U.S.C. § 2423(d) for facilitating travel for illicit purposes.
State-level charges (such as child endangerment or contributing to the delinquency of a minor).
Even if the parents believe the adult “loves” the minor or that “nothing sexual will happen,” prosecutors can still treat this as child exploitation or grooming facilitation.

🇬🇧 3. UK Side
Once in the UK:
It is a serious criminal offense under UK law for an adult to engage in sexual activity with anyone under 16.
If the U.S. minor is under 18, UK authorities can still take protective action under child safeguarding laws, especially if grooming or exploitation is suspected.
The adult could face arrest in the UK and extradition or prosecution there or in the U.S.
