There’s no way to enter the embassy and speak with someone in person because if you mention anything related to a visa, they just tell you to do it online. Security won’t even let you in. However, after making several calls, someone finally answered and told me that this is a common issue. They advised me to try explaining my case at the airport.
I’m not even sure if I can reapply for a new visa since the one I received is still valid/active.
Anyway, I think I’ll try flying with the visa I have.
I did it twice, but I didn’t get a reply. Tomorrow, I’m going there in person. However, I wanted to ask anyway if there’s any chance they will change it smoothly.
