An important tip is to make sure you use an authentic website when applying for an evisa for a trip to India. We used indiansvisa.org.in
Also a tip, you’ll need to upload photo ID. If you have an iphone we found out that since 2021 they have changed the format for photos from Jpeg to HEIC as this reduces the storage required on your phone. However many websites do not recognise the HEIC format. You can get around this by changing the format on your phone. Go to settings>camera>formats and change from High Efficiency to Most compatible.
