Hi,

I came across a process involving the expedition of an F4 visa category. In this one has to prove the need for an expedition and have a good reason for the expedition.
I am looking for any help that would help me understand what are the categories that are considered by USCIS for a fast expedition and it would also be helpful to know how and what documents I need to show for the expedition.

A little background of my case - I am the only family member in my home country. My F4 file was placed in 2017.

Thanks
