Is there any reasons to worry about visas ?

Hello everyone,

I write this post because I see a lot of anxiousness around visas, people are scared and everything so I want to have your opinion guys.

We see many people getting their entry denied but from what I read there’s always a reason. Overstays, insufficient amount of money, visa runs, etc.

In my case, working in aviation in western, I came 8 times on visa exempt in one year for periods between 1 day to 27 days. I never had any trouble, secondary inspection or anything. Not even a question.

So is this just luck ? Or as long as we don’t abuse the system and follow the rules, we have nothing to worry about?
