as far as i know..to apply to lousina tech for instate... you have to complete 20 credits or something like that (not sure).. but a lot of nepalese get their instate in lousiana tech..even it is ranked third in nano engineering in US. best of luck. And  it's quarterly...If you get instate fees than the money you earn in summers can last you for your whole year...

maybe you can contact them
