Meet your National Representatives- 2018-2020

Meet your National Representatives- 2018-2020

Countries with ten or more SIL members are entitled to elect a National Representative (NR). NRs are elected for three-year periods and are responsible for sending applicants from their country to the SIL student competition. In some countries, they assist the General Secretary-Treasurer in collecting annual dues from members of their country in their own currency and transferring the total amount to SIL’s bank account.

Note that the National Representatives listed below are for contact relating to SIL matters in their country.

A list of all SIL National Representatives is available here.
