ETA Validity and Duration of Stay

• Multiple Entries: Holders can enter and exit the UK multiple times during the validity period.
• Duration of Each Stay: Up to six months per visit.Wikipedia – Die freie Enzyklopädie

• Visit the UK for tourism or to see family and friends.
• Attend business meetings, conferences, or short-term training.
• Engage in short-term studies (up to six months).
• Transit through the UK to another destination.

These permitted activities are detailed in the UK’s official ETA guidance.

An ETA does not allow:

• Paid or unpaid work in the UK.
• Long-term study programs exceeding six months.
• Marriage or civil partnerships.
• Access to public funds or benefits.Wikipedia – Die freie Enzyklopädie+3Migration and Home Affairs+3Wikipedia+3

Important Considerations

• Each traveler, including children, must have their own ETA.

• Travelers must use the same passport for both the ETA application and travel.

• An ETA does not guarantee entry into the UK; border officials make the final decision.Investopedia+2Migration and Home Affairs+2Immigration Blog+2Wikipedia

These considerations are emphasized in the UK’s ETA factsheet.
