Hi, thanks to anyone that has answered my questions before.

I have a few questions before I make an application in a few months time.

1. Whatsapp chat logs, does it matter if its a screenshot or just a chat log? i.e. we've had new phones over the years so can't screenshot several years back
2. Relationship evidence (cards, flight tickets, photos etc) + marriage certificate - this has to be submitted in its original copy. Will all the evidence be returned via tracked mail?
3. The English language requirement - my partner has a degree from City University so we plan to use NARIC - do I only need to pay for the statement of comparability?
