Unpaid/late PCN

Hello,

I submitted an application for a visa extension two weeks ago to extend my tier 4 visa. I'm an American currently living in the uk. I am very concerned about my application and I'm hoping to get some help.

Basically, last September I received a PCN for parking without a permit. I had updated my address on my logbook for the car, but the notices were being sent to my old address and I never received anything. Yesterday, I began to get nervous I'd missed something out on my application, so I rang the county and sure enough, my parking fine had been referred onto bailiffs. Immediately after hearing, I called the bailiff and paid in full; however, because I found out after sending in my application, I didn't disclose this information.

I'm also concerned that because the fine was referred to bailiffs, that this may be considered a non custodial offense and my application will be refused. I did receive one other pcn in June, but that was paid immediately.

I really hope someone can help. I'm sick to my stomach with worry.

Thank you!

Under the convictions and other penalties section, do PCNs for parking infractions need to be declared? The only answers I can seem to find are from several years ago.

I already submitted my application before finding out I had an old unpaid PCN, but I paid the minute I found out. If it needs to be declared, how do I send in a correction?

Thank you.
