I hold valid Indian passport. I got married recently. We are applying for schengen residence permit / visa.

How important is last name change for my wife in the context of applying for visa? Can she keep her fathers last name as in passport?

What is the difference between last name and spouse name for a lady after marriage? 

We have just applied for marriage certificate.

Please see the screenshot.
