Fiance visa - photos

Hello,

My partner (US) and I have been in a relationship for seven months. She spent five months living with me in the UK (she moved in pretty much after our first date!) and I've just got back from visiting her and her family in the US. We got engaged on the trip and are planning to apply for a fiance visa for her to return to the UK and for us to be married.

We have message records, phone records and can have both of our families and friends (who've all met and love my fiance!) provide written statements around how our relationship is genuine. We have hotel receipts for trips taken in the UK (which my fiance's social media posts corroborate), cards written on valentines, b'days etc.

However, we have very few photos of us together in the UK (maybe 3 or 4). My partner is extremely camera shy. We do have photos of the places we've visited together, but usually only I'm in them. On our recent visit to the US we took a lot more photos of us together (aware that we need to take more pictures for this eventuality), including shots of me with her family on various trips. Will our lack of photos in the UK likely be grounds for a rejection?

Separately, we plan to have a small registry office service in the UK when she arrives. This will involve a few close friends and family (including her mum who'll make the trip from the US). Likely no more than 20 or so people for a meal at a local restaurant following the service. We plan to have a bigger party further down the line. Will evidence of such a small service put us at a disadvantage? We really don't want to organise a massive wedding while we're living in different countries.

Finally, while we lived together I initially didn't update my council tax status from single occupancy assuming a foreign visitor would not count as a permanent resident. After she left, a friend asked about this and I checked with the council. I paid the backdated council tax and the council's records have been updated. Aside from this updated information, we have no written evidence of my fiance living with me in the UK. Should this evidence (which was latterly amended) be submitted or will it raise a red flag given I didn't notify the council immediately? I have however paid the bill, so another view could be that I wouldn't do that if my fiance wasn't genuinely living with me.

Aside from the areas outlined above, all other criteria are safely met.

Any advice on the questions above would be greatly appreciated.

Thank you!
