Payment Plan

My wife is eligible to apply for Naturalisation, my question is, can it paid in monthly payments?

I was told you can but searching doesn't bring up anything other than children citizenship.

No it cannot.

You were told wrong. You cannot even pay monthly for children's Citizenship.

The full amount is payable at the time of online application submission.

If you hold two credit cards, and one of the cards give you the option to transfer balance interest free for 12/15 months. You can pay the application fee from one card, and then transfer the balance (which has the offer) to one you used to make the payment and you'll get 12/15 months to pay the liability interest free.
