Yes, you can configure more than 1 country code on your WLC as needed.
This may help you to see how to do this config on your WLC
To work it properly you should have reliable connection between WLC & AP.

Yes and no.
Yes if both the AP and the WLC are configured with the same Regulatory Domain.
If your WLC has multiple Regulatory Domain configured, only common channels will be enabled.
Hiand Leo Laohoo,
So it's possible to install a WLC in Japan and AP install in Singapore? The WLC in Japan able to control the AP in Singapore?
So it's possible to install a WLC in Japan and AP install in Singapore?
So will the Japan-based WLC also control APs in Japan? If the answer is yes, then I'd say it will not work efficiently.
So you mean it can be done but less efficient right? Because of distance? or because of the number of AP supported by the WLC?

Ok, let me paint you this picture.
Let's say you have a WLC in Japan. And you have APs in Japan and in Singapore.
When you configure your WLC to have both APs in the Regulatory Domain, it means that the WLC has to turn OFF channels which are not allowed in both countries. This only leaves common channels left enable.
If you want to manage APs in different countries, it is best you group APs with the same Regulatory Domain together or you provision separate WLC.
This is not a "Cisco thing". This is common sense mandated by rules and regulations by the country where the APs are installed.
Controllers and access points are designed for use in many countries with varying regulatory requirements. The radios within the access points are assigned to a specific regulatory domain at the factory (such as -E for Europe), but the country code enables you to specify a particular country of operation (such as FR for France or ES for Spain). Configuring a country code ensures that each radio's broadcast frequency bands, interfaces, channels, and transmit power levels are compliant with country-specific regulations.
Generally, you configure one country code per controller, the one matching the physical location of the controller and its access points. However, controller software release 4.1 or later releases allows you to configure up to 20 country codes per controller. This multiple-country support enables you to manage access points in various countries from a single controller.
Note Although the controller supports different access points in different regulatory domains (countries), it requires all radios in a single access point to be configured for the same regulatory domain. For example, you should not configure a Cisco 1231 access point's 802.11b/g radio for the US (-A) regulatory domain and its 802.11a radio for the Great Britain (-E) regulatory domain. Otherwise, the controller allows only one of the access point's radios to turn on, depending on which regulatory domain you selected for the access point on the controller. Therefore, make sure that the same country code is configured for both of the access point's radios.
For a complete list of country codes supported per product, see http://tools.cisco.com/cse/prdapp/jsp/externalsearch.do?action=externalsearch&page=EXTERNAL_SEARCH or
Follow these guidelines when configuring multiple country codes:
•When the multiple-country feature is being used, all controllers that are going to join the same RF group must be configured with the same set of countries, configured in the same order.
•When multiple countries are configured and the RRM auto-RF feature is enabled, the RRM assigns the channels that are derived by performing a union of the allowed channels per the AP country code. The APs are assigned channels by the RRM based on their PID country code. APs are only allowed to use legal frequencies that match their PID country code. Ensure that your AP's country code is legal in the country that it is deployed.
•The access point can only operate on the channels for the countries that they are designed for.
Note If an access point was already set to a higher legal power level or is configured manually, the power level is limited only by the particular country to which that access point is assigned.
•The country list configured on the RF group leader determines what channels the members would operate on. This list is independent of what countries have been configured on the RF group members.
You can configure country codes through the controller GUI or CLI.
Hi Saurav, so a WLC in Japan HQ, it control AP in Japan, the WLC also can control the AP in Singapore branches? I just want to know it can be done and how well is the performance.
Just to add... When I have done numerous wireless country deployments, I would have a dedicated WLC for each region like US, EMEA and APAC. Now depending on the individual countries regulation for channel and power, I would possible have a WLC for each country due to the fact that like everyone mentioned, the WLC will use the most common channels and power levels.

So the best practice is to have a WLC for each country for the best performance,
Bunch your APs to the WLC with the same Regulatory Domain.
For instance, you can have a WLC that manages Australia and New Zeland. Another WLC that does nothing but Europe. Another WLC that do US, Canada, Philippines, etc.
You just need to make sure UDP 5256 and UDP 5247 are allowed from the subnets the AP's are in to the management of the WLC.
