In UK on visitor visa now to EU?

Hi,

So my pinay gf is in London now on a 6 months visitor visa. We'd like to go to Portugal after the 6 months, can we apply in London for the EU visa?

In a word ...... No
"Non residents such as travelers and tourists currently on a visa in the UK, cannot file their visa application at the Schengen embassies in the United Kingdom. Instead, they should apply for a Schengen visa at the appropriate Schengen embassy in their home country".

Bummer that's a costly trip to the embassy

Can you apply for a further 6 months visitor visa in the UK while still in the UK ?

Well we got the UK visa while on holiday in Singapore so maybe there's a closer country than Philippines we can go to to apply for the schengen visa
