My original plan was to travel from Türkiye to Czechia and Poland for 7 days. With this plan, I applied at the French embassy (which represents Czechia in my country) for a single-entry Schengen visa. After receiving my passport, I found that I was given a 22-day multiple-entry visa valid for 1.5 months.
Now, if I travel to Czechia, then Poland, then to Türkiye, and then go to Greece, and afterwards to Bulgaria, will there be any issue when making that second Schengen entry? Will it cause any problem for future Schengen visa applications since I didn’t mention a second entry in my original plan (which was for a single entry).
Note: I previously traveled to Schengen three times on single-entry visas issued by a non-French embassy. This is my first multiple-entry visa, even though I applied for a single entry one. This is also the first time I’ve applied at the French embassy.
