Can a blind person do a post-doc in the humanities? I’m about to finish my PhD in Sociology. I’m from Pakistan, and I’m totally blind. My PhD research was quite interdisciplinary. I studied factors influencing environmental concern about environmental problems in Pakistan, as well as factors influencing environmental behavior at home. Now I want to do a post doctorate from anywhere in Europe, North America, Australia or New Zealand. 

Can my blindness be a factor in acceptance / rejection of my application?

If not, what should be my first step for finding a post doctoral opportunity? My research interest is in the domains of environmental sociology and environmental psychology.
In the United States there's what is known as the Americans with Disabilities Act (ADA)

which prohibits discrimination based on disabilities and mandates reasonable accomodations. Full or partial blindness will definitely fall under that category, and so they are legally prohibited from discriminating against you and if hired will work with you to help out. Many other locations have similar laws. In Canada the laws vary from province to province, but most of Canada has similar laws. Many (although not all) European countries have similar laws or regulations as well.
