Dear House..please how long is the processing time for German Tourist Visa..Thank you

Guys, i was recently refused a tourist visa to the UK, and the notice of decision said that i had not clearly explained how my income earnings were derived, despite my payslips and offer letter, promotion letter and bank statements.

I included my biz reg. details and the eco said i need to prove that the money in the bank is mine entirely.

I have been advised that i should do a review, by an immgration consultants ( Harvard Consults) at a fee will assist me in challenging the decision of the ECO.

What is your take.
