I want to share few suggestions to all prospective students, especially those who want to study & work in USA. In terms of working in the USA after completing your degree, there are many restrictions that students get to know only after coming here. I have seen often times students only inquire about these their final semesters and start worrying. Know beforehand and decide if you really want to come here.
Canada is a better choice if you want to look for job hassle free and eventually become resident. Yes, the market is much bigger in USA but so are the restrictions, especially if you complete a technical degree in USA, recently there have been major changes.
Note: This post is not to discourage you about USA but for you to know all the restrictions that apply. Of course thousands of Bangladeshi students eventually make their ways in USA. But after reading the article, it is your decision to make if you want to fight through these concerns. I am also writing how to fight these. And I would encourage you to speak with students you know in USA who are on OPT and H1b already to reconfirm and get more ideas.
If you only want to study in USA and get back to Bangladesh, then by all means, come to USA first. Then all these concerns don’t apply to you.
