I'm trying to get to Barbados. Please I really need an advice. Can anyone help with the answer to the following questions;

Which country should I apply through? and which countries do you suggest I apply to for transit visas?
Please also what document do you provide to show as proof for ties in Nigeria as it required that I proof that? I am a recent graduate.

Kindly help for those that have successfully travel out of Nigeria. How do you get a history history to Proof your case?

Kindly advise

Thank you so much
