Just thought I would post as much information as I have been able to gather through the journey which I found painful as I just didn’t know anything and would of appreciated some detail. So here goes. I hired an agent which isn’t cheap and he did very little work, but he knew what he was doing so that is what I paid for. Knowing what I know now I would of done it myself but it is too scary without that knowledge, hopefully information here will give some confidence to others. It’s a personal choice. Use an OISC regulated agent https://www.gov.uk/find-an-immigration-adviser/search-for-an-adviser if you go down that route. Just share my personal experience, not an expert and do not guarantee the accuracy. Happy to edit the post from the comments of others. The agent told me as long as you satisfy the law then they cannot refuse an application, never hide the truth or tell an untruth, if there is a problem best to tell then up front and give an explanation. You have to prove: You have met. Plan to marry with 6 months Somewhere to live (UK has minimum housing standard requirements) Financially independent and not to rely on public funds Both live permanently together after married Immigration rule here: https://www.gov.uk/guidance/immigration-rules/immigration-rules-appendix-fm-family-members I’ve put in the Section Titles I used to send the documents but obviously they will be different for everyone. Documents required that I will cover: Statements of intent, I’m told theses are very important though not documented in "the rules" Proving relationship Financial independence Housing Freedom to marry The wedding Documents must be original, if not then must be certified (stamped by a solicitor or lay person) as true copies (your not allowed to send your passport so you need a true copy of all the pages that have something on them like visa, don't do blank pages) or countersigned by the issuer of the evidence, e.g: bank statements must be through the post to be seen as the original, I printed them off the internet so had to go into the bank and they stamped each page as true copies and signed. Send a copy of all documents or you won’t get the originals back, basically send 2 bundles.
