Yes, one visit will clear your void completely! There's no way to check, but if you've been through any town's gates and the game was saved (that is, no resetti appeared and either the other player ended session or you left by train), you're clear and safe to go.
Just to add: even if you visit a town that has less than 10 villagers, your void will be cleared any way. The difference is that you'll leave a "gift" for the player to find on the next day, but any other town you visit later will be safe.
Just another tip about the void: if you have multiple villagers in your void and pay a visit to a town that has less than 10, the one animal that will move there is random among the ones inside the void; the others will be erased completely. So if you someday happen to want to pass on a villager that is in your void to someone, make sure to clean your void before the move out, so when they do, it will be the only one there. Then do not visit anyone else until you go to their 9 or less villager filled town and voila!
I hope yall don't mind me asking here since it's relevant, but what is the villager void? :0

OH I see!! Thank you both of you, that actually explains a lot. I knew that villagers could move into other's towns while connecting but i didn't know how it worked. That's quite interesting, I'll be sure to try and start clearing out my void as well before i plan on connecting from now on :0
Not to be a downer, but previous threads seem to indicate that void clearing isn't a 100% certain thing. Here are a few older threads about it on TBT:

I don't have much experience with it myself, since I don't frequently trade villagers with other people, especially since the amiibo update. But I've heard several users claim they've cleared their voids and still given someone an unwanted move-in, so I would be cautious about relying on it too heavily.
If I ever get a spare cartridge, I might have to do my own experimenting. I wonder if anything changed after the update...
One more question: if I have villagers in my void and someone with less than 10 villagers in their town visits my town, can they pick up one of my voids?
Not 100% sure, but I believe it's a risk. The voided villagers I've received were from people that visited me, but I believe it works the other way around too?
The implications of creepiness in picking up a voided villager by visiting someone else's town - haha! Like those stories of taking home spirits from visiting a graveyard. (My imagination works overtime and I can come up with all kinds of backstories, which is probably why I like this game so much )
