The State Department has asked US citizens traveling to India to exercise increased caution in India due to crime and terrorism. It says in its briefing on March 8, 2019
Do not travel to:
The state of Jammu and Kashmir (except the eastern Ladakh region and its capital, Leh) due to terrorism and civil unrest.
Within 10 km of the India-Pakistan border due to the potential for armed conflict.
Indian authorities report rape is one of the fastest growing crimes in India. Violent crime, such as sexual assault, has occurred at tourist sites and in other locations.
Terrorists may attack with little or no warning, targeting tourist locations, transportation hubs, markets/shopping malls, and government facilities.
The U.S. government has limited ability to provide emergency services to U.S. citizens in rural areas from eastern Maharashtra and northern Telangana through western West Bengal as U.S. government employees must obtain special authorization to travel to these areas.
If you decide to travel to India:
Do not travel alone, particularly if you are a woman.
Review your personal security plans, and remain alert to your surroundings.
Enroll in the Smart Traveler Enrollment Program (STEP) to receive Alerts and make it easier to locate you in an emergency.
Follow the Department of State on Facebook and Twitter.
Review the Crime and Safety Reports for India.
U.S. citizens who travel abroad should always have a contingency plan for emergency situations. Review the Traveler’s Checklist.
State of Jammu and Kashmir
Terrorist attacks and violent civil unrest are possible in the state of Jammu and Kashmir. Avoid all travel to this state (with the exception of visits to the eastern Ladakh region and its capital, Leh). Sporadic violence occurs particularly along the Line of Control (LOC) separating India and Pakistan, and in tourist destinations in the Kashmir Valley: Srinagar, Gulmarg, and Pahalgam. The Indian government prohibits foreign tourists from visiting certain areas along the LOC.
India and Pakistan maintain a strong military presence on both sides of the border. The only official India-Pakistan border crossing point for persons who are not citizens of India or Pakistan is in the state of Punjab between Atari, India, and Wagah, Pakistan. The border crossing is usually open, but confirm the current status of the border crossing prior to commencing travel. A Pakistani visa is required to enter Pakistan. Only U.S. citizens residing in India may apply for a Pakistani visa in India. Otherwise, apply for a Pakistani visa in your country of residence before traveling to India.
Incidents of violence by ethnic insurgent groups, including bombings of buses, trains, rail lines, and markets, occur occasionally in the northeast.
U.S. government employees are prohibited from traveling to the states of Assam, Arunachal Pradesh, Mizoram, Nagaland, Meghalaya, Tripura, and Manipur without special authorization from the U.S. Consulate General in Kolkata.
Central and East India
Maoist extremist groups, or “Naxalites,” are active in a large swath of India from eastern Maharashtra and northern Telangana through western West Bengal, particularly in rural parts of Chhattisgarh and Jharkhand and on the borders of Telangana, Andhra Pradesh, Maharashtra, Madhya Pradesh, Uttar Pradesh, Bihar, West Bengal, and Odisha. The Naxalites have conducted frequent terrorist attacks on local police, paramilitary forces, and government officials.
Due to the fluid nature of the threat, all U.S. government travelers to states with Naxalite activity must receive special authorization from the U.S. consulate responsible for the area to be visited. U.S. officials traveling only to the capital cities in these states do not need prior authorization
