I have a person in Russia who helps me in my business when I visit that country. Now I would like that person to visit with me my customers in Latvia, Spain, Germany, and France, but not all of them in the same trip, so I would need for this person a multiple entries business visa. We plan to make about 4 or 5 business trip during this year and I don´t want to apply 4 or 5 times for a single entry visa. Is it possible?
