Yes, we are thinking of waiting for sometime as well before contacting them about address change.
My timeline is a little messed
My husband was a PR in canada and we met here, since our parents were not agreeing to the wedding he decided to go back to india when his PR expired.
so I applied first in april and in May I received the letter that he should apply in india from a travle document to see if his PR is still valid, he applied got called for interview but was rejected since he did not stay the minimum time required (2 years). Then I re-applied for him in July on the 5th, and I got my sponsorship approval within 15 days, and file was received at new delhi on july 22nd. Since then it says on application received, and in december beg we saw medicals received, but it still does not say in processing...
