Can we keep the UK as an option for master's studies in architecture?

Yes, you can keep the UK as an option for your Master's in Architecture.

Your Bachelor’s degree in Architecture with a 6.49 CGPA (on a 10-point scale) is generally acceptable for UK universities, though some may have higher grade requirements. Most universities require an IELTS score of at least 6.5 overall (no band below 5.5), so you'll need to prepare for this if you haven't already.

Some universities may also expect completion of ARB (Architects Registration Board) Part 1, but this varies. Your 9 months of work experience is a plus and may strengthen your application.
