It is preferred that your recommender has worked with you and knows you in person on a daily basis. However, there is no hard and fast rule. Try not to compromise on any aspect of your application - as these aspects do play out heavily during your application selection process so you may need to make sure you know your recommender well enough.

Picking someone long distance can make your application reviewer wonder whether you actually do get along well with teams in person - so you may need to find a way to address that in case you pick this Holland person.

Good Luck!

Thank you
