I applied for a Spanish tourist visa with my girlfriend last month and got a rejection letter two days ago. The only information provided was the ticking of box number 10 "The information submitted regarding the justification for the purpose and conditions of the intended stay was not reliable". No other box was ticked.
The reason for rejection took us by surprise because we thought our itinerary was the strongest aspect of the application. We were going to attend a Padel holiday training camp that was happening at the same time as Premier Padel Malaga, so we were also going to watch the tournament finals. Our hotels and flights were pre-paid; we provided tickets for the finals, an invitation from the camp organizer (1, 2), and some pre-paid sightseeing tours. Do you have ideas on what would have been on the officer's mind when deciding to reject the application based on this reason? And thus, do you have any idea on how we can provide more proof regarding the purpose of travel? Our purpose of travel is legitimate, and I'm sure there's something we failed to deliver to the officer, but I'm not sure what it is at this point, so I'm seeking your help. I know there's another post regarding this reason but it states that it's often accompanied by "there are reasonable doubts as to your intention to leave the territory of the Member States before the expiry of the visa". In my case, it's only reason 10. How often this happens?
Here's more background in this post.
Although it will be impossible for us to make it to this camp, there is another similar camp happening in Madrid in September, and we plan to appeal or reapply hoping to be able to attend that event. Is it possible/advisable to appeal this rejected visa application for the records and also submit a new application for the new dates, or can an appeal be submitted for alternative dates? More importantly, how to know if something about our situation is wrong in their eyes, and thus we need to wait until changing it before reapplying, or if there's something that we failed to prove, and we just need stronger proof before reapplying.
