United States and United Kingdom.
There are many in Syria - I do not know them but I can tell you where they live.
Also there are many in Maritania, Morocco, and Yemen.
If you are interested in studying I can give you the email address and name of a scholar who could advise you for what would be best (one on one learning or madrassa).
Really if you want the early stepping stones to become a scholar these madrassas would give you a great footing to stand on:
Dar al-Mustafa - Taught by some of the great Sunnis of Ahlul Bayt (radi Allahu `Anhum) in Tarim Yemen. They teach many subjects I do believe.
Mahad al-Islamiyah - They teach most Hanafi fiqh and some other things in Damascus Syria, Yusuf has more information.
al-Qarawayin University - Shaykh Hamza Yusuf has lectured here. Has some of the most outstanding scholars of the Ummah including Ustadh Ahmad Zweetan. They teach Maliki fiqh, and `aqeedah, etc. (the ciriculum is posted above).
But you must have phenomenal Arabic skills to goto the Universities firstly, and secondly have memorized much of the Qur'an for some of them.
Dar al-Mustafa is a really good place.
There are also places in the United States - such as a new mini- al-Azhar university which insha Allah is going to have al-Azhar's certification in Atlanta Georgia which is coming soon.
