Perhaps you can't. All apps are not available at all stores, as described in the following text, lifted from an online article:
There are quite a few good apps in the iTunes App store that, unfortunately, aren’t available to international users. For instance, if you are not located in the US, you cannot install the iBooks reading app from Apple on your iPhone, iPod Touch or the iPad because iBooks is currently only listed in the US iTunes store.
Similar is the story with Adobe Ideas (a sketching app), ABC Player (from ABC News) and Zinio (for reading magazines) – they are all brilliant apps that are completely free but you can’t add them to your iPhones or iPods if your iTunes account is linked to a country other than the United States.
You can see a listing of such apps in your iTunes store but the moment you hit the install button, it will pop-up a warning message saying “Your account is only valid for purchases in the [your country name here] iTunes store.”
There are some fairly complicated hoops to jump through in order to get access to free apps from another Store, but it works only for free ones (note: as I've read, but never verified); I've heard of no way to do it for paid apps.
