If you will apply for a fiancee visa you have to pay 500 (P47,500.00). Don't be scared as long as you have complete documents. Some of the member in this forum they got their visa within 6 weeks, don't wait to go home until your visa will expire, better to go home earlier so that you have still time to lodge your application and if it takes only 6 weeks for your visa to be process then you can go back in the UK without hassle.
