Some universities may have rolling admissions, meaning they accept applications until the places are filled. Others have firm deadlines, often several months before the January start date.
To find the correct application deadline, you MUST:
1. Identify the specific universities and programs you are interested in.
2. Check each university's website. Look for their admissions section, often labeled "How to Apply," "Admissions," or "Undergraduate/Graduate Admissions." The application deadlines will be clearly stated there.
Don't rely on generalized advice. The application process is crucial, and missing the deadline could mean you can't start in January.
