What if a family member like a child is not present at the time of interview in Islamabad embassy of Germany?

Hi Yara,

I hope you’re fine and doing well. My name is Fitrat currently living in Germany. I wanted to ask you, that: What if one of a family member such as a child from ex wife, who has been already booked an appointment for a visa interview is actually because of some family reasons won’t present at the time of an interview or won’t allowed or maybe he/she didn’t want to come to an interview to the Embassy of Germany in Islamabad. Will his/her absence affect the process of the other family members? 
 

Looking forward to your kind answer with some details. Thank you very much! 
 

Very respectfully 

Z. Fitrat
