Would you like to apply for unemployment benefit and have worked in your country before?
Apply in your country to your unemployment office and ask for a PD U1 form. This is a form with a summary of contributions previously paid for unemployment benefit. This form is international, can be issued in your mother language and does not to be translated. In order to receive an extension of the benefit, you must have paid contributions (before coming to the Netherlands) for at least 4 years out of the last 5 years, of which you must have worked for at least 52 days (52 days of contributions) each year.
