To resolve the reasons for the denial , I am going to write letter that shows more evidence of my ability to support my self and my family in canada :
Im thinking in only applying for her , do you think she will have better chances to get the visa approved if she is the only applicant than applying as a family ?
- You need to demonstrate that you have funds to support yourself in Canada for one year, that is to say: tuition fees + at least 10k in your bank account.
- When you reapply, you have to explain why you applied for your son and daughter and how it would help you and them in the future.
- You have to show them you have property or business in your name, this can serve as ties to your home country.
- If you'd like to immigrate to Canada, I suggest you apply through Express Entry as doctors are in high demand in Canada.
- Your application suggests an obvious attempt to immigrate to Canada rather than study. If you will reapply, you must address that concern with plausible reasoning or else you might be refused for "Purpose of Visit".
Feel free to PM me if you'd like like to know what I know from my experience in our language.
Good luck!
