Just FYI, IELTS tests are also being suspended in Canada until end of April. (By Humber college, George brown and few other Centers)As a matter of fact, from the top 10 biggest providers of immigrants, 5 have IELTS restrictions in place.
TOTAL restrictions:
China
Saudi Arabia
PARCIAL restrictions:
USA (6 locations)
UK (1 location)
United Arab Emirates (2 locations, but probably the biggest ones)
I do think all of these will result in less than a 3% impact in the overall pool, based on the distribution of percentages of each of these countries. To be quite honest, the only way for us to see a major impact would be if both USA and India stopped applying IELTS tests across the entire country.
