1. Ya, we can try. and if she got refused with a TRV let say because of Covid, can that be considered as immigration barrier?
I was always the one who go to her (Philippines) since I like to see my other relatives as well. I also went to school last year and did not think of inviting her since my income was not stable.
2. Well, she is a Filipino, countries that she can visit without applying for a visa prohibit same-sex relationships as well. So, Canada is only country I can think of because I can help her with a visa.
1. I don't know that they'd make any distinction between a visa refusal for covid vs other refusals. I'm not really following visitor visas right now, right now the difficulty may be whether they're accepting applcations for 'non-essential' visits at all. By the way there will be an announcement today:
https://www.canada.ca/en/immigratio...h-provides-update-on-travel-restrictions.html
They have said they will announce measures to allow entry of "certain extended family members of Canadian citizens and Canadian permanent residents,
including those in an exclusive dating relationship of at least 1 year."
There is zero chance, I should think, that this will not extend to cover same sex relationships as well.
When the announcement is made be sure to read the details and not just press reports, they are often wrong.
Now I don't want to get your hopes up too much, we've no idea what will be needed to document and it may be very difficult to qualify. But at least you'd be able to apply and if denied, at least you'd have that part of the requirement satisfied. (And if accepted, all the better and you could just get married in Canada and apply inland.) But apply carefully, you wouldn't want a refusal on this to be because they don't believe your relationship.
But the good thing is you'd have a basis to apply for a visa now as a visit based on exclusive relationship. (Again though all these comments possibly premature as no details yet announced)
2. Yes, there may be few options. But doing the research to document helps your case. (Including for example refusals to other countries can't hurt, although much more difficult in covid times.)
Good luck.
