Thank you so much for your reply.I am a permanent resident.My husband is in Indian army and he will show his proof of returning back to India after my delivery.In general, having a spouse join you in Canada if you are a PR or citizen then having your spouse join you is not considered an H&C reason. The big issue is that ties to Canada will become even stronger when you have a baby and the spouse is unlikely to leave. We are seeing more approvals of TRVs for spouses of citizens and PRs due to covid so it is definitely worth a try but you should have a plan B.
Anyways if i apply for TRV,how much is the processing time?
