Hi everyone,

After receiving approved status on github student developer pack, I received this message.

Thank you for your patience during this process. After reviewing we have determined that your account is ineligible for GitHub purchases due to restrictions under U.S. economic sanctions. For this reason you will not be able to proceed with your GitHub transaction.
If you disagree with this decision, or want to learn more, please go to https://docs.github.com/en/github/site-policy/github-and-trade-controls.
Apologies for any inconvenience.

But after following this link I did not find any restrictions in Russia. It says there that the restrictions apply only to Crimea and Dombas.
