It seems that Dr. Declan Butler senior reporter at _Nature_, ( Web: http://www.nature.com
Blog: http://www.declanbutler.info/) has intention to write an article about this matter (Visa problems of iranian scientists) for the journal. Of course we should collect more and more cases.
In fact he has a contact with french physician and has collected some cases about the visa descrimination of iranian researchers.
Please, if you know any more similar cases of visa obstructions (not just france), write here or send an email urgently to firstname.lastname@example.org (send email in the case of French visa difficulties)
I strongly believe that we also should put the item of free circulation of Iranian scientists as an important discussion item of ICSU (International Council for science). We should mention the compromise and historical actions of ICSU with this issue.
