Everyone who works in the UK needs a National Insurance (NI) number.  Although you can apply for a job before you get your NI number, you are advised to apply for it immediately as it will be easier to obtain a job if you have one.   

Information about National Insurance numbers and how to apply for one can be found on  the Directgov public services website.

International students at Swansea University can obtain help and advice about obtaining a National Insurance number from the International Student Advisory Service (ISAS).  Please see their web pages on working during your studies.
