Salma07:
I didn't get any response on this thread so I made some enquiries on social media. Apparently, visa appointments for Spain are suspended indefinitely due to strike action by Spain consulate staff: https://theedinburghreporter.co.uk/2022/03/spanish-visas-may-be-delayed-due-to-strike/
Apparently, BLS has been given instruction not to release appointments for May until staff grievances are addressed by the Spanish government. Hope this is helpful to someone...
Thanks so much for the research and update. I read the link and did further checking too. It seem it’s the embassy in London that this applies to. Is there a way to confirm that the ones in Nigeria are joining the strike too?
