I from North Africa, and only have my country's citizenship. I am doing my PhD in the USA. There is a workshop I want to attend in France, and I am confused as to which visa I need to go there. (It's one month long)
Last year I applied for a business visa, and the French visa embassy in Chicago insisted that I get a work permit or something. I had very short time to get this sorted out, and I ended up missing the workshop. I have some time this year, and would like to get it right.
So, what kind of visa should I be applying for?
