Since they are tropical and have no real dormancy period you can prune throughout the year. Since I am able to move mine outside during the summer I have been doing all of my work during the growing season. Re-potting, hard chops, pruning and cuttings all in the summer when they are in active growth. My indoor lighting is far from ideal and I find that growth slows considerably for me over the winter so I do not do much work then.
Unless you have quality supplemental lighting I think I would wait. Ficus are known for losing some/all of their leaves after a move and yours may, although mine never have. You should look into some lighting as our homes are generally rather dim, even if it does not seem so to you.
I hope this helps some and welcome to the site.
