Do i postpone for the 4th time?

Have you asked her how busy/booked up April is so far? I would be tempted to wait it out, depending how easily you can switch your suppliers (if any) etc. Can you go to another nearby registrar if your March date can’t go ahead and you can’t get a new booking at your current one? Up to you!
We’re waiting until the last possible moment (4-5 weeks before) to make any postponement decision for our beginning of May wedding. If it would put your mind at ease though and the uncertainty is stressing you out then I would probably postpone now ??

Weve ended up rebooking because they only had one date left in April. We've booked a reception for July so we're doing it all separately but at least we will be married before the visa runs out.
