Hi everyone,
Finally I did it, now you can filter Codeforces users by country.
Just go to this page and select the country and click view table.
I found that many Codeforces users didn't write a country in their profile,
but I have a TopCoder Tools website and I have all TopCoders countries in my database,
and I assumed that many users have the same usernames in TopCoder and Codeforces.
So if the country is unknown for a Codeforces user and I found a TopCoder account with the same username,
I assigned the TopCoder country to this Codeforces user.
I know that this way could assign someone the wrong country, but it will happen with low probability.
Also I got the country using this way for 1318 Codeforces users with unknown country, which I think it's very good number.
If you have just added or changed your country, you can go to this page, and write your username and click update my country, and it will be updated in my database too.
You don't need to enter your country in my website, just update it in Codeforces and do the above steps.
Anyway, if you found that your country is selected incorrectly, please send a message to me and I'll fix it.
I hope that you will find this useful.

Good job!
Waiting for new features :)

6 users from the Japanese table and 8 users from the Iranian table are now updated in my database.
Thanks!
I'm running the script which updates the countries again now, but it may take couple of hours.
Sorry for this mistake.
And as you see in the main post, I used my TopCoder database to get the country for some users.
Anyway, it's fixed now, you can check it here.
I think you should change ir5's country from Iran to Japan.
Edit: Also Mohammad_jrs and piloop are from Iran. Their TopCoder handles: Mohamad_jrs and piloop
