"I don't think people fully understand what it's like to date someone from another country and the rules behind that and the visas behind that," Katie, 30, explained in a series of videos Wednesday on her Instagram Stories.
"I think right now Blake can only be here for 60 days before having to go back to Canada," Katie said, seemingly referring to how a Tourist Visa works.
"So we really do have a lot we have to look into -- and we just haven't yet -- before we can plan really anything else."
The Season 17 The Bachelorette star then asked her followers going through a similar situation to give her some advice.
"But I am curious, if you are dating somebody from another country -- whether Canadian to U.S., U.S. to Canadian -- I would love to know your experiences with that, in terms of all that fun legal stuff that we are holding off on," Katie said.
Katie appeared to stay in Blake's country for about a week before flying back to Seattle and then heading to New York, where she is currently staying.
Katie expects Blake, a wildlife specialist who spends a lot of time in Africa, to join her in The Big Apple, and then Katie previously revealed on Instagram she'll be moving into a new San Diego, CA, apartment by herself on September 1.
The pair had also told Us Weekly their goal is to "jump around for a bit" observing each other's lifestyles and interests as well as learning more about each other's hometowns in order to figure out their eventual "anchor spot" and what works best for the both of them.
Although Katie and Blake are clearly looking forward to the future together as a happily-engaged couple, Katie confirmed earlier this week on her Instagram Stories that she's not in a rush to wed.
When Katie's sister asked when she and Blake plan to get married, Katie posted her response on Instagram and she wrote in reply, "Not soon at all. He's Canadian... So we have a lot to work through first."
"It's hard to say the impact of that in the real world, [if he didn't pop the question], because you go through so much and you want to take this very seriously -- and a proposal and engagement is very serious," Katie told Us.
"I didn't come here to find a boyfriend. I can do that on a dating app," she added. "So it's hard to say if we would have survived just as a dating couple."
