I am based in India and currently residing in Oman. If I have a plan to do the SAT, I will choose the test date according to the college application deadlines.

Foreign colleges accept application via Early Decision (ED) & Early Action (EA).
We don't have the entire article on Early Action (EA) and Early Decision (ED).
Check the below URL to know about EA & ED.
