What changes did you do between the two applications..
I meant how did you address officer's concern for rejection in your second attempt
My application was rejected because the VO wasn't convinced that I would leave Canada at the end of my visit because of three reasons -
1. Family ties in Canada and in country of residence
2. Purpose of Visit
3. Personal assets and financial status
To address these,
1. I wrote a cover letter stating the purpose of visit. I included a detailed day to day itinerary and the expected cost.
2. I am visiting my sister-in-law's family. So I provided her birth certificate and my wife's to prove that they are siblings. I also got a invitation letter from my sister-in-law stating these
3. I submitted the details of all my short term and long term assets. I have also showed that the total estimated cost of trip for 15 days can be managed with my monthly salary.
4. I also shared the leave letter from my firm stating that I applied leave and will return to home country after the visit.
