1. For how long does your brother want to visit? What is the purpose of his visit? 2-3 weeks, purpose of visit is visiting a friend.
He must include an invitation letter from his friend + copies of the friend's immigration status and passport.
He must prepare a day-by-day plan of what he intends to do during his visit with expense estimates like a typical tourist + to meet his friend. And, prove that he can pay for this itinerary + airfare.
Do NOT limit his purpose of visit to only wanting to meet his friend.
2. Will his wife and daughter accompany him? No, But what are the pros and cons of them visiting with him.
Your brother does not have any strong ties.... only his employment + his wife and daughter.
I suggest that his wife and daughter do NOT apply.
3. Does he own any property/land? Or have a rent agreement in his name? No he does not own anything, as everything is still on my father's name.
He cannot show your dad's property/assets as his own.
Does he have a Power of Attorney to represent your dad for these properties/land? If yes, has he used this PoA?
4. Does he live with any other dependent family like your parents, in-laws? Yes, My father lives with my brother.
He must include proofs that he/his family/your dad live at the same address + any evidence to show he takes care of your dad. For example, if he pays for medical insurance of your dad.
5. Are his savings in liquid cash or locked-in? All the saving is in liquid cash but it is scattered in various accounts and those accounts are joint accounts like one joint account( me and my brther) has 500,000 INR, another my brother and my sister in law has one joint account that one has 300,000 INR.
There must be no large, last-minute deposits + nothing borrowed from anyone.
Your brother must include letters from each of the joint bank account holders stating he can use the funds in that account for his Canada visit.
Then my father has 200,000 INR in his account. We have immovable asserts of worth 75,00,000 (150000)
He cannot include this as he does not own it.
Your brother must prepare his documents properly as he does not have strong ties (except for his family and employment) + no travel history.
Two questions which the visa officer may ask:
1. Why your brother wants to visit Canada for his first trip abroad + to meet a friend (if he does not have any relatives in Canada).
2. Why would your brother want to spend a significant part of his savings on a holiday to Canada?
I recommend that your brother must prepare a very strong purpose of visit.... and not just to meet a friend halfway across the world
