University of Manchester is a great place for any student. I myself am a foreign student and I felt very welcomed into the community. There are people from many countries and it is a great opportunity to expand your horizons.
As for the teaching the style is very similar to other UK institutions. The quality of lecturers was good in general although there were many exceptionally bad and exceptionally good outliers.
University offers many supporting services and provides students with many opportunities such as part time work.
The city itself is amazing and I would highly recommend Manchester for your university life.
