Really appreciate your response.
We're in a genuine relationship, and in my opinion, common law seems to be the right path, however, due to the strict regulations in Vietnam, it is a bit difficult to provide all of the "reasonable" proof of common law, i.e. shared utilities bills, etc.
I am able to obtain a Confirmation of Residence from the local authority to prove that we both reside at the same address, and planning to use that to support our application.
I was fortunate enough that my company allows me to WFH, from literally anywhere in the world, but it's the timezone difference that makes it pretty hard for me to maintain the work-life balance, since I have to work late at night, it's not healthy, so I'm hoping and planning to travel back to Canada and reside within Canada with my partner (once her visa has been granted of course). Planning to state this fact as well.
My concern is right now I'm not entirely sure if we should apply as Common law partners, or Conjugal partners - as we also seem to fit within the Conjugal stream but I learned that it is way more difficult to prove Conjugal.
Include proof and an explanation that utilities are split between the 2 of you since both being on utility bills was not possible and/or not common in Vietnam. This type of arrangement is fairly normal for even married spouses. The goal is to show that you are living in a situation/relationship where utilities are treated as shared household expenses.
