Hi,
Yes true, OCI will take some time.
Apply for an Emergency visa, Go to
https://indianvisaonline.gov.in/, select Regular Paper visa form>>>> Regular paper visa application and start filling in the form..
Visa type- ENtry
purpose - I selected - 1st option from the drop-down
You can select 6 months - multiple entries, photographs will be needed digital and printed both you can check the requirements. (If you are using any booth they are pretty much easy ones as they have an option for Indian visa pics. Upload a digital photo and submit an application.)
Once you have submitted an application take a printout of the application form, stick a photo and sign below as well as at the end of the form. Scan the signed application along with all the documents and email them to
visa.london@mea.gov.in
Make sure your application has those emergency documents attached. On appointment, You will be asked the emergency reason.
Documents I submitted: Old surrendered Indian passport, surrender certificate, Current passport, Medical documents, 2 passport size photos along with the main application signed form.
Timeline Example: If you submit today, most probably tomorrow you will receive a letter for an appointment and that would be for the day after tomorrow. After submission, you might need to wait for few hours but Visa will be granted on the same day
Hope this will help .
