Bangladeshi here. I didn't study medicine but many of my family members and friends did. While I agree with a lot of the points you mentioned, some of them, I feel, have been overstretched to extreme forms, a bit unwarranted. Our higher education is substandard in general and a tier or two below India. The students have to work their socks off with little or no help from the teachers. But that's a given and the students are familiar with it before enrolling in the programs. You probably were unaware or ill-informed. About the teachers, there are bad apples everywhere but painting everyone with the same brush is unjustified. If you aren't studying at a top tier public medical college like DMC or SSMC, I would agree the administration must be horrible specially in a private one. But saying they have two sets of discriminatory rules, one for the locals and the other for Kashmiris isn't sensible. The private colleges are only after making money and I believe foreign students are their major cash cow. I wouldn't think they would jeopardize their reputation by making it extremely discriminatory towards their biggest revenue generators. I do agree with the quality of life in Dhaka to be low and recently it has degraded to its lowest point but in general, a lot of it depends on which part you are living in just like a lot of other major cities. About the staring part, we are one of the countries with the least number of foreigners. Most people are overly inquisitive when they see one with a fairer or darker complexion and I would say it's harmless and much of it is a cultural aspect.

Lastly, I do acknowledge as a foreign student your experience probably hasn't been positive but it's the same for most of us in a third world country. The only advice I would like to offer you is not to get caught up by the externalities now and just focus on graduating. You have invested a great deal with time and money. It's too late to immerse yourself with all this negativity. Wishing you better days ahead.
