Here are my useful tips:

1. Try to get all your worrying out of the way beforehand.
2. Be confident - what you think is what happens.
3. Be decisive, aim for your goal like an arrow.
4. Always create a warm atmosphere; one person I stood in line with for the visa even came up to say hello and introduce himself, even though we didn't even look at each other in line. We went to McDonald's together afterwards, and with two other girls as well.
5. Smile, even if you don't feel like it.
6. Be vigilant and persistent, create the illusion that you are the center of the universe and that people should follow your example because you are VERY friendly and VERY confident.
7. Be as calm as a cowboy before a shot, focus on the details and only on one goal.
8. Remember that you are unique and there are no other charming and pleasant people like you.
9. Know that only you can change everything, and you are the one who will definitely get the visa.
10. Watch "Tom and Jerry" before the consul, I don't know what the trick is, but the effect is amazing, some who sat nearby even laughed very heartily.
    What you definitely shouldn't do (proven in practice!!!):
11. If you are asked something, answer exactly as you wrote in the electronic application, i.e., if, for example, you indicated that you study at Skaryna University, then UNDER NO CIRCUMSTANCES answer that you study at Gomel University, only at Skaryna University.
12. NO answers like: I hope, I don't know, I'm not sure. There is sad experience (This is not a JOKE!)
    (write to me if you have anything to add from the real experience of other people. Let's help others...)
13. When filling out the electronic application, double-check everything again. There have been cases when, due to incorrectly entered data, people got confused during the interview, which led to a refusal directly at the interview.
14. Read the IEC newsletter carefully again!!!
15. You need to be at the Consulate 1 hour earlier than the time you were assigned. There is a possibility of traffic jams, emergencies, etc., and this way you will have a little time in reserve. If you don't make it today, you won't make it this year at all!
