Hope this will help....
My wife is a naturalized british and i applied schengen visa last year for we will celebrate my birthday in France...
i applied online for the schengen visa. French embassy has outsourced the process and they use TLS (not sure bout the name)... Since i am an EU citizen's spouse, its quite simple...brought our marriage certificate without any verification or authentication from the philippine embassy and her passport... That's it.. No charge for the visa.. We just paid the post for we want it to be delivered for we live far from london..
