Okay. Perfect. She has been returning after staying in her home country for a significant amount of time.
Nonetheless, do wait until April/May before you apply for her super visa. As her extension was approved for her recent TRV stay, she will most likely be approved for a super visa too (she'll need to clear medicals, etc of course)
Thank you dear Bryanna.
I am still looking for the answer about what should go in purpose of visit. I am thinking to do it a in 2/3 lines with some genuine general reason like spending summer her and probably going on a road trip to the country side within Canada or a family road trip to the US. What is you take on this?
