Workers going and coming from abroad can be split into three categories
| EEA | Members of the European Economic Area NIM33003 and NIM33004 |
| RA | Reciprocal Social Security Agreements NIM33014 |
| ROW | Rest of the World NIM33019 |
The general rule in any case whether a person is working in the EEA, non EEA countries with which there is a RA or non EEA countries with which there is no RA is the same - you pay contributions in the country you are working in
