International secondment - Changes you need to report

If you are on secondment and there is a change in your situation, you must let us know without delay. We will then see whether the change affects your social insurance position.

You must report the following changes to us:

You move house

If your social insurance position changes as a result of your move, we will let you know within 2 weeks. If nothing changes, we will send you a new E101 certificate showing your new address.

You start working fewer hours in the country where you live

If you start working less than one day a month in the country where you live, you must report this to us. If your social insurance position changes as a result, we will let you know within 2 weeks.

You can report changes by email. Include the following details:

• your name;
• your address;
• your date of birth;
