Hej !
Så här står det i mitt visa som jag fick.
När jag ansökte på https://indianvisaonline.gov.in/evisa/tvoa.html
On presentation of ETA to the Immigration Officer on your first arrival, an e-Visa stamp (valid for 60
days from the date of first arrival in India) would be endorsed on your passport.
Mvh
