So im planning to invite a friend to visit me. I want him to visit me twice. Once for 15 days in february 2020 and then for 75 days in may/june. Is it possible that he applies for the visit visa once only and be able to get a visa from february to june with multiple entries allowed? His total duration wont exceed 90 days.
Edit: My friend has had many schengen visas before and never over stayed
