Paying for subscription for NA account as an expat

[VisualDeadlock]

So I am a bit worried that I will have a problem paying for my sub using my CC when my free period ends.

This is my situation:

I currently live in Hong Kong. When I had first signed up for an account on the FF14 page, I was able to put down Hong Kong as my country of residence. I then purchased the game, but square enix account management defaulted me to the Amercias region. Which is OK, I prefer using my US card anyways.

When I digitally purchased the game and obtained my codes, you have to go to the mogstation to register your account etc..At that time, Hong Kong was not available to me from the dropdown list (I looked and triple checked). So I selected US since I didn't have any other option.

Now I am wondering, after my free trial period ends, will I have a problem paying for my subscription?

I have 2 options

1) Use my US card, which is using the US address that I used for the SE account (my former address in the states). But, I am wondering if it will fail to go through because my IP will be in Hong Kong

2) Use my HK CC. This will match my IP but will not match the US based address.

Anyone know?
