On the validity of visa, the guidelines says that the initial period of visa may be up to a period of one year or the period of treatment, whichever is less. It can be extended up to one year by state governments on production of medical certificate or on advice from the reputed specialised hospitals in the country.
Regarding granting visas to attendant or family members, the new regulations insist that visa may be allowed only to the spouse, children or those with blood relations with the patients.
“Not more than two attendants may be allowed at a time and the foreigners will have to get themselves registered with the local authorities well within 14 days of their arrival.”
