Make your visa application as early as possible (for example, one month in advance)! The processing time for work and study visas varies by country, but it can take 2-3 months or even longer! In your visa application, make sure your passport is valid for at least one year beyond the application date! Even if your visa application is accepted and you receive your visa, you may still be turned away at the border if your passport is damaged! Your visa application may be rejected. While there is no obligation to provide an explanation for the rejection, some countries may provide a written and/or verbal explanation.
