I am US F1 student, and I am soon going to graduate. I want to call my parents on my graduation. What documents do I need for that? Your help will be highly appreciated.

Congrats Sajhafan on your coming graduation. You need to request the international adviser to write an invitation letter for you parents(Give parents name) to visit your graduation. Tell them that it is required to show in the US embassy while applying for visa. Another document you need is a bank balance.
Good Luck.

Nabubabu thank you so much for your reply.

.Bank Balance shouldn't be necessary from your side. As you are a student, it is understood that you haven't involved in illegal off-campus work and you don't have thousands of dollars.

In my case, I just sent a letter from International office.

you bette ask your parents to have strong documents back home.

Prakash ji what are those strong documents that they need to prepare back home? Is it just a property or something else.
