Christ is risen!
I'm intending to convert to Orthodox when my priest gives permission God-willing. I've been attending Vespers and Liturgy since last October and I've been beginning to make a home in my local (English-speaking) parish mission.
Now my husband and I are about to move 2 hours drive away. I would be willing to make the trip back each week, however the place we are moving to has a Monastery about 15 minutes drive away and other Orthodox churches that are about half-an-hour away. The problem is that they are different jurisdictions. The parish that I have started connecting with is Antiochian, whereas the Monastery is Serbian and the other churches are Greek. I've also started to feel very connected to my priest and the local parish, so I feel like I would be disloyal worshipping at a different church.
Well, I can't speak to your feelings, but in fact your priest and local parish's loyalty is to the Orthodox Church, so as long as you are worshippig at a different Orthodox
Church, there is no disloyalty in fact.
What to do? Is it permissible to continue on the conversion track with my current priest and parish mission, but not attending quite as regularly now eg. once a month and then for the other weeks attend the Serbian or Greek churches for Divine Liturgy?
This is not a question of loyalty per se, but the fact is that since your current priest knows you best, he should know better how to handle your transition. If, for instance, the Serbian and Greek Churches celebrate services in Serbian and Greek, and you don't speak Serbian and Greek, and the priest knows that will impede your progress, he might want you back in his parish more often, but if it will not affect your journey into Orthodoxy, he might be fine with once a month (and contact via, say, email). Again, its a question of what you need now, not a question of loyalty.
Or should I be really shifting into the closest parish, even though it is a different jurisdiction?
The problem of shifting is sort of like switching colleges before graduation. You should at the very least visits the local parishes. Sort of like visiiting relatives.
I do plan to discuss this with my priest, but I wanted to get a general feel for whether one/other answers is totally un/acceptable.
It is totally acceptable either way, following your priest's advice.
