How many EB3 ROW do they process each year?

http://immigrationroad.com/green-card-tracker.php provides priority dates earlier than you.

How many visas are allocated for EB3 ROW each year? And how many are already used for this year

each country has a cap of 7% - approx 2500 visas. if that limit is hit for any country then it becomes Unavailable for the rest of the year for that country. since demand is high for india, china, mexico and philipines - they are called out separately and all other countries are put under RoW.

So a more appropriate answer will be for your country it will be 2500 visas (approx) + any spillover at the end of the year.

EB3 ROW gets approximately 35K visas every year.

(FY2009) EB3 total was c. 40k visas you can check here
