We are considering having an International Membership section of BIVR, possibly akin to the Participating Member status which the NCRA affords some of our members (and others around the world), which of course does not allow EU nationals to work in the US without the relevant consents.
Once Council is satisfied that the qualifications have been gained by undertaking similar examinations to those we ask all our members to undertake here in the United Kingdom, you should be eligible to transfer in to BIVR with full membership.
Of course, BIVR membership does not confer upon International members any right to work in the UK. To work in the UK, they will need to obtain the necessary visas/work permits required for non-UK citizens. Therefore, international members should not use the fact of their BIVR membership (once granted) to attempt to gain said visas/work permits.
