Securing a VISA has become much more difficult now?

Is it true that securing a VISA has become much more difficult after 2016 in US.
How was your experience ?

It’s not true and it solely depends on your profile, the University, your finance and the way you present yourself to the visa interviewer. If you are planning to study in a university like ASU then congrats; you have a good profile and there is hardly any scope of visa rejection. My visa interview was less than 5 mins. I was asked about the name of my course and the University, my current job role( as i am working at that time) and my finance. That’s it. Present yourself well and be confident. All the best !
