Do i have to submit original passport for student visa from India?

if yes,

what should i do, if i need to travel another country during that time?

Thank you.

To obtain a sticker/stamped visa, yes, of course you have to submit your passport. You need to plan your other overseas trips accordingly. Usually CIC allows 1 month timeframe to submit the original passport. Hopefully, you can plan your submission accordingly. I heard it takes about 7 business days for the passport to be returned to you.

If it is an online visa application, you need to submit the passport after they ask for it and not when you submit the application. You will have (I think) 30 days to send the passport from the time they ask you to submit the PP.
