Overview Singapore has classified the foreign countries with which it holds diplomatic relations into two categories. India falls under the category of “Assessment Level I countries”, implying that Singapore visa for Indians is not required for the holders of diplomatic, official and service passports. Also, Indian nationals are eligible for a 96-hour visa-free transit in Singapore. Sceptical about dealing with middle-men and tedious paperwork? You can apply for your Singapore tourist visa online through NitSa Holidays for quick and hassle-free results. Also, since the entire application process takes place through a credible platform, as opposed to the traditional approach, the risk of visa fraud and fake visas is also negated.
