10 Visa Free Destinations for Indian Citizen

Indian travellers may rule the declining rupee but there are other perks to being an Indian citizen. Holders of Indian passports have visa-free and visa-on-arrival access to about 52 countries and territories around the world. At least 28 of these nations allow Indian passport holders to visit without a 

pre-issued visa. 

In many cases, an Indian citizen's country of residence determines the degree of access to other countries. Indian citizens holding permanent resident (Green Card) status in the United States do not require visas to visit Canada, Mexico and some Caribbean islands. Indians of particular professions with a residency in Gulf Cooperation Council (GCC) countries are exempt from visas to enter the United Arab Emirates. Indian citizens do not, similarly, need a visa to enter Nepal or Bhutan.

1. BHUTAN

Bhutan, the happiest little nation in the world, is among the most sought-after Himalayan destinations for tourists but the Himalayan mountain kingdom is very conservative when it comes to tourism. Travel writer Pico Iyer mentioned it in his book, Falling off the Map, as one of the world's remotest places. Until recently, Bhutan restricted tourist numbers. Though that has changed.

2. BRITISH VIRGIN ISLANDS

Most Indians need to look up the British Virgin Islands on a map. They lie in the Caribbean Sea, and include over 60 islands and keys, of which about 43 are uninhabited. Indian citizens are granted a 31-day visa-free stay in the British Virgin Islands for tourism purposes. One of the best ways to visit the islands is by cruise ship, as many cruises operate from the United States to the nearby US Virgin Islands. There are no direct flights between India and the British Virgin Islands. 

Approximate cost of round trip flight: INR 1,60,000 (via Paris and Saint Maarten) 

3.COOK ISLANDS

The Cook Islands lie in Polynesia, off the coast of New Zealand. They are named after Captain James Cook, who discovered them for the western world in 1770. Since 1965, the islands have been self-governed with free association to the government of New Zealand, which controls the islands' defence,Rarotonga International Airport, the main port of entry to the Cook Islands, is connected to Auckland via daily flights and weekly flights from Sydney, Fiji and Los Angeles. 

Approximate cost of round trip flight: INR 1,60,000 (via Singapore and Auckland).

4. DOMINICA

Not to be confused with the Caribbean nation known as the Dominican Republic, the island of Dominica was the last of the Caribbean islands to be colonized by the British. It has beautiful hiking trails, rainforests and beaches with great opportunities for snorkelling. Indian citizens are allowed to stay for 22 months without a visa. 

Approximate cost of round trip flight: INR 2,00,000 (via Paris and Saint Maarten)

 

5. EL SALVADOR

El Salvador, the most densely populated country in Central America, lies between Guatemala and the Honduras. Volcanoes, mountains and cloud forests offer plenty of nature discovery and hiking opportunities. Old colonial towns and UNESCO World Heritage Sites beckon heritage tourists. Indian nationals are permitted to stay for a maximum of three months without a visa. 

Approximate cost of round trip flight: INR 1,44,000 (via Paris and Miami)

6. GRENADA

The beautiful Caribbean islands of Grenada offer much to tourists in the form of beaches, waterfalls, historic forts and spice gardens. Indian tourists can travel visa-free in Grenada for up to 90, but must show proof of sufficient funds to cover the cost of their travel.

Approximate cost of round trip flight: INR 1.60,000 (via London and Miami).

7. HAITI

Haiti is off the travel map for most tourists owing to the devastation left by the 2010 earthquake. One of the poorest countries in the Western hemisphere, its current political situation and concerns over the safety of tourists has prompted many countries to issue strict travel advisories. That said, Indian tourists are welcome without a visa for a maximum stay of three months.

Approximate cost of round trip flight: INR 1,52,000 (via Dubai and New York)

8. JAMAICA

Jamaica is the most populous of the English-speaking Caribbean countries and its easygoing culture, cuisine and music, besides its many beaches, are attractive to tourists. Indian tourists can stay without a visa on producing a passport valid for six months and sufficient proof of funds and onward travel. 

Approximate cost of round trip flight: 1,53,000 (via Dubai and New York/ Toronto)

9.MONTSERRAT 

Not to be confused with the Spanish region of the same name, Montserrat is an island in the Caribbean southeast of Puerto Rico and once a popular resort. Since 1989, hurricanes and volcanic eruptions forced its closure but the island is slowly limping back. Indian citizens must show proof of citizenship but can travel visa-free on furnishing proof of onward travel and adequate funds. 

Approximate cost of round trip flight: 1,30,000 (to Antigua, via London) and a 15-minute air-hop from Antigua to Montserrat (about INR 5,000)

10. MICRONESIA 

The far-flung Federated States of Micronesia are a group of 607 islands in the Western Pacific Ocean, comprising the states of Yap, Chuuk, Pohnpei and Kosrae. It is considered one of the most remote and beautiful places in the world, with pristine coral reefs, quaint cultures, exotic food and picturesque islands. Indian citizens can travel visa-free for 30 days upon producing proof of sufficient funds, onward travel and accommodation. 

Approximate cost of round trip flight: 2,04,000 (via Hong Kong, Guam and Truk)

What You Should Write Down During a Class Lecture

photo www.lifehacker.com

Your professor says an awful lot of things during class. You can't possibly write it all down, nor should you. To take the best notes (and ace your exams), pay attention to your professor's cues—conscious and subconscious. 

Part of a great guide on note-taking strategies by Brett and Kate McKay on The Art of Manliness, these are the tell-tale signs that you should be writing down what your professor is saying.

o        Anytime the professor says, "You need to know this," or "This will be on the test."     Duh.

o         Anytime the professor repeats himself.

o         Anything the professor writes on the board or includes in a Powerpoint slide.

o         Anything the professor repeats very slowly so that it can be taken down word for word.

o         If your professor starts talking more quickly, or loudly, or with more emphasis.

o        Watch for language that shows relationships between ideas. These sorts of points are often where professors get their exam questions from:

o        first, second, third

o        especially, most significant, most important.

o        however, on the other hand.

o        because, so, therefore, consequently .

   

o       Another great tip is to write down any examples or hypotheticals the professor offers, because you'll probably see a similar one on your final, especially if you're taking math or science classes or are in law school. Examples are also key in computer science/programming classes.

Sometimes, depending on the professor, paying attention is the hardest part. But keep your ears perked for these keywords and points and you might find yourself with more effective notes.
