Visitor Visa for parents

[ddazzlers]

Hi,

I am a student in us and thinking of inviting my parents to my graduation, for which they need to get a tourist visa. As I am still a student i cannot sponsor them so how can they get a visa?

Another question is if they get visa will it be any issue for my sister to get her student visa next year?

[peace]

They should show very strong income and assets to qualify for self financing.
If they do not have that then it won't be possible.

You can only send an invitation letter.
