Hi there!
Last Dec 2006 I applied 6 months visit visa to UK and was refused last Jan 2007... I never appeal at all but I applied for another visa which is spouse visa last Nov 2008 and up to now still waiting for the result..Tomorrow my visa application will turn 16 weeks so hoping next week I will receive a good news and not the negative result..I'm keeping my fingers crossed for it as always!
Caused of refusal was I am minor applying for a visit visa to UK and will be traveling alone.....
God bless you and I wish you all the luck!
