General Information

Visitors entering India must possess a passport valid for at least 6 months after their date of entry into India. There should be at least two blank pages in the passport.

An entry visa is essential for all those visiting India. There are several types of visa, including Conference, Tourist and Business Visas. Those travelling specifically for IUCr 2017 should apply only for a Conference Visa.

When to Apply

For most countries, the time taken by embassies to issue a Conference Visa is normally 10 days, and the visa is valid for three months from the date of issue by the embassy (not from the date of entry into India). For applications from citizens of Afghanistan, Iraq, Pakistan, Sudan, Foreigners of Pakistani Origin and Stateless persons, the time taken is 60 days and the visa is valid for one month.

Fill in your Passport Details on the Congress registration website

Visa Applicants from (1) Afghanistan, (2) Iraq, (3) Pakistan (4) Sudan (5) Foreigners of Pakistani Origin and (6) Stateless persons must fill in their passport details on the Congress registration website by 31 May 2017 to get their visa in time.

For applicants from all countries, the details should be of the passport which you will use to travel to India. If you supply the details of one passport to the Congress and apply to the Embassy with another passport, the Embassy will reject your visa application.

Fill the Visa Application Form

Indian Embassies, Consulates and High Commissions now require visa applications to be made online from the Indian Government website:

Please note that this website is operated by the Indian Government, not the IUCr 2017 Congress. Here are some tips on using that website:

  • Make a note of your temporary reference number. If the website gives error messages or freezes, you can try later using your temporary reference number to retrieve your partially filled form.
  • A visa application form will be generated with the High Commission Logo at the top. Print 2 copies (and another one for yourself) and sign. Save the document in case you need to reprint.

For participants from Pakistan:

  • The port of entry into India should be Delhi, Mumbai or Chennai only. Hyderabad is not an allowed port of entry for Pakistani citizens.
  • Pakistani citizens holding two passports should apply for a visa on their Pakistan passport.

Get your Supporting Documents

The supporting documents required for a visa application are:

  1. Two passport-size photographs
  2. Letter of identification from your institution or employer
  3. Four Letters of permission from Indian Government Ministries for holding the conference
  4. Letter of Invitation from the conference authorities

You should obtain items 1 and 2 yourself. Items 3 and 4 can be obtained from the Congress website as described at point 8 below after May 15, 2017. All the documents should be submitted together to your nearest Indian Embassy or Consulate. All these documents are described in more detail below.


You will need to provide two 50 mm x 50 mm photos. Please ensure they are of your entire face from the top of your head to your chin, and that this distance measures between 25mm and 35mm. If this is not followed your application will be rejected.

Any Other documents required by Indian Embassies for Conference Visa

In addition to the documents described above, some embassies may require additional information. Please check the website of the Indian Embassy in your country under the heading ‘Conference Visa’.

Accompanying Persons

Accompanying Persons are not entitled to attend the conference technical sessions and should apply for a Tourist Visa. They can of course benefit from the discounted hotels and participate in the Opening Ceremony, social events, lunches and mixer of the Congress.

The application process for Tourist Visa is much simpler than Conference Visa. No letter of invitation is required. Accompanying persons can use the e-Tourist visa facility at the website

For a Tourist Visa, the purpose of visit should be stated as Tourism. Mentioning “Conference” on a Tourist Visa application is incorrect and will lead to the visa application being rejected.

Letters of invitation are issued only to delegates attending the Scientific Congress; not accompanying family persons.


Enquiries can be sent to We can help with information, but the Congress cannot influence the embassies in any way. It is the responsibility of the participant to get his/her visa.
