well.. There might be a few. But in order to use those, you would need to live in their area. As you probably know, for this extension you need to provide rental contract (if applicable) or blue book if not (your wife's house) plus providing photos of you living in the space. Plus an almost certain to happen home visit from immigration, for at least the first application in that area. You can't just shop around, going to a hotel in the area to get a tm30, for that office to process the extension. You need to actually live there, and be able to prove it. So if your luck, just as mine, means the office that service your area won't accept international transfers alone (like most of them), then you need to think long and hard about that ๐
