Good day, officer!

I am Maegan, 19 years old and a student, residing in the Philippines. I would like to accompany my 74-year-old grandmother next year and see your beautiful country at the same time. We both wish to go on a vacation and visit my aunt in North Carolina. However, she has been granted a multiple-entry tourist visa in May 2015 and went to the US in August 2015, and went back to the Philippines in December 2015, while I haven't applied for any type of US Visa yet. I believe that the possible reasons why she was granted a visa was because she has been travelling to different parts of Europe and Australia since 2007, and her financial stability as well. Is it possible for a student like to be granted a visa? Considering that I haven't traveled outside the Philippines yet, but I believe my financial assets are enough.

Please let me know.
Thank you very much and have a good day!
