For the summer of 2024, the easiest Schengen visas to obtain are issued by Iceland, Switzerland, Latvia, and Italy, as these countries have lower rejection rates. Conversely, Malta, Estonia, and Belgium have some of the highest rejection rates for Schengen visas, making them the world's worst countries to apply for these visas.
Well, since the summer in Europe often extends beyond August and can last as late as October, one can start planning ahead. If you go by the reports of Schengen Visa Statistics, you will find a variance in visa rejection rates among different countries. Applying to countries with lower rejection rates can enhance an applicant's chances of success.
