I will make the following adjustments:
- Make the title itself the link, instead of using the text "find out more". Thus, the original question becomes irrelevant. This will also be better for SEO, because your links do not include generic text like "click here" or "find out more".
- Images are not informative – use an image that significantly differentiates between "domestic" and "international". To check if you've done a good job: hide the text and swap the images – will users be able to determine which is which?
To answer your specific question – assuming you decide to keep the "Learn More" URL, I do not see any difference between displaying it above or below the image, as long as you respect the Gestalt Proximity Law and keep the link close to the image. – so it is clear that they are associated.
