3 Options...

1. You would need a family member out here you can get you down on visit-visa (Father, mother, brother or sister) ; Valid - 15days, can b extended

2. Hotel Visa (Which once again, would be available only if you stay with the hotel through out your visit, which would turn out to be quite expensive)

3. Business visa (3 months, if i am not wrong) which can be done if a company calls you over by showing their invitation letter.
