What is the procedure for availing exchange facility for participation in international conferences/seminars?
Applicant should submit to an authorised dealer a letter in duplicate from the sponsoring institution (from the applicant in case of self-employed professionals). The application should indicate the name, address, nationality and passport number, duration of visit, foreign exchange required and a certificate from the employer that the expenses are being borne by them.
