information request (Dubai)

Dear All,

Happy new year !

A group of people I know in Lithuania is travelling to Dubai for the first time.
They are as follows :
American father
Lithuanian mother (not married to him)
American daughter (previous wedding)
Lithuanian daughter (having the lastname of the father, and daughter of the lithuanian woman).

I know that Lithuanian, they have to go to some line to get the migration validation to go in the country. What about americans ?

Isn't there any possibility to get a fast track and to avoid all the lines ?

In advance, thanks for advice and answers

Best Regards,
