We are paying for all their travel expenses that includes travel airport food while they’re here necessity meds if they need it they are all 14 12 and nine
The three nieces will be staying at my house like I said I will provide everything the father can’t come as he has work and Lebanon the reason for us bringing the girls is to visit her or their family here in Canada and we’re having Ramadan soon Also their grandma has passed so we would like to bring them to the grandma’s grave but I mean half the coming years to see Anuties and uncles cousins etc.
No they have not travelled international but they do you have a passport and I do you they are travelling with my brother who is not their father he will leave Canada to go to Lebanon to pick them up and bring them back to Lebanon
Their mother has deceased
Yeah, no, sorry. I know you were simply asking about documents for a visa application in the near future, but everything you've mentioned here, from our experience with seeing TRV refusals, makes it very very improbable your nieces will be granted any TRVs. I would rather you spare yourself the time, money, and anxiety for what will be a fruitless endeavour. Sorry if it sounds harsh, but that's the most realistic scenario to come out of this.
To be approved for TRVs, applicants need to show, with evidence, not promises, that they will leave Canada after a reasonable amount of time. These are what they have against them:
1. Very young
2. From a country with known conflict and a high number of asylum cases
3. No mother = even less family ties in their home country
4. No international travel
5. Lots of family in Canada = potential overstaying in Canada
6. You are paying for their expenses, not their own father = they are not dependent on him but you = stronger ties in Canada
Plus everything PMM said above, and the processing times out of that region, specially with current manpower constraints, the timelines you mentioned don't make much sense.
