I was supposed to welcome a scientist originally from India and currently working in Switzerland. He had travelled to the UK in the past and obtained his visa in a couple of days. However, as of 01.09.2010, the visa applications are sent to Paris and the sticker Visa is issued from there (earlier they used to be issued from Geneva) and as such it takes a minimum of 2 weeks.
And, after 2 weeks, the visa was rejected. He had included all the details requested. The trip was paid entirely by his host laboratory in Switzerland. The UK Border Agency had my phone number and e-mail and could have checked in 1 minute that this was a genuine scientific collaboration. Instead they took the decision to prevent a fully funded and highly skilled scientist to come in. Is that for the good of the UK competitiveness?
