can't change region due to pending payment that can't be paid

i have i cloude subscription is pending whichc need $3 and in mybalance i have 4.66$

You say you have $4.66 which is more balance than the $3 your subscription wants, so there should be no problem with Apple automatically taking what you owe and then you doing one of the things below to bring your account to zero.

#1. If you still have a valid credit or debit card from your original country, purchase an item for slightly more than your balance. The remainder will be billed to your card, leaving you with nothing in your account balance. This is the only solution for you to empty your balance if cannot contact Apple Support. This method is the easiest and you get to use your money yourself instead of giving it to Apple.

#2. Ask Apple Support to remove and keep the balance. Live support is not available in all countries.

- Click on the special empty-balance request, chat link at the bottom of this support article ➔ Check your Apple Account balance - Apple Support

- General Apple support and service contact ➔ Contact Apple Support - Apple Support If live support options are available they will show near the bottom left. Telephone numbers may only work when calling from the same country. If numbers show as colored links, click on them for more options.

- With an iPhone, iPad, or Vision, you may be able to chat using the Apple Support App if it is available in your country ➔ https://apps.apple.com/app/apple-support/id1130498044

If you can neither add a payment method nor contact Apple, your alternative is to create a new Apple Account when you are in the new country. Avoid doing that if at all possible. It may cause many complications with your current account content.

When changing account regions there’s a full set of guidelines in this support article ➔

Thank you for reaching out. 🤗

There are many parameters that need to be taken before changing regions because currency valuation is not the same across various regions.

If you are changing regions:

• Spend any remaining Apple Account balance: You can spend your remaining balance on the App Store, other Apple services or in some countries and regions, Apple products and accessories. If you’re not sure if you have a balance, check your Apple Account balance.
• Clear a low Apple Account balance: If your balance is less than the cost of a single item in the App Store or other Apple services, learn how to clear your balance.
• Cancel subscriptions that block a country or region change: Cancel any subscriptions that block a country or region change, then wait until the end of the subscription period. 
• Wait for pending activity to clear: Wait for any memberships, pre-orders, movie rentals or Season Passes to complete. You can cancel a pre-order. Also wait for any pending refunds from Apple to process.
• Check your Family Sharing status: If you’re a part of a Family Sharing group, you might not be able to change your country or region. Learn how to leave a Family Sharing group.
• Have a valid payment method ready: You might need to enter a valid payment method for your new country or region. If you don’t want to enter a payment method, wait until you're physically in your new country or region. Then create a new Apple Account.
• Redownload your content: Some types of content might not be available in your new country or region. Redownload your apps, music, movies, TV shows and books on any devices that you might use to play or read them in the future.
• If you need to empty your balance: Contact Apple Support to request a reset of your account balance to zero.

Good luck! 👋🏼😉

Or did you get that backwards and you actually owe $1.66 more than the balance you have?

If that is the case then you need to pay what you owe before you can effect a country change. The best way to deal with this is to add a credit or debit card which will be debited for exactly the amount you owe, leaving nothing in your account. Read the changing country article I posted earlier.

If you do not have a payment card, see if you can join a family sharing group for a short while where the family Organizer's payment method is used. To learn how to join a Family Sharing group, read the section "Join a family group" in this support article --> How to set up Family Sharing on your iPhone, iPad, or Mac - Apple Support

If you can do neither of those, this article outlines how to redeem an Apple Gift Card or App Store & iTunes gift card --> Redeem your Apple Gift Card, App Store Card, or App Store & iTunes Gift Card - Apple Support The problem with doing that is you cannot get a card for exactly the amount that you need and you may end up having to either find a way to spend the remainder or giving Apple your money.

Your final and ethically least desirable alternative is one about which I already posted and that is to abandon your current account and try to set up a new account in your new country.
