Mrs Constance OGBA

Good afternoon, i am writing from the French school in Accra to make an enquiry on behalf of the French school in Lome. They have 2 french inspectors who have to go to our sister school in Equatorial Guinea on a mission. Since you do not have mission in Togo we would like to know they can acquire their visa's from Ghana. Do they have to come physically to your embassy or they can send their passports over. If yes, what are the requirements please. Thank you in advance for your assistance
