oscargare, check this code I used. Basically you need this part to add to the code:

if( ! WC()->session->has_session() ){
					WC()->session->set_customer_session_cookie(true);

add_action( 'plugins_loaded', function(){

		if( class_exists('WCPBC_Frontend') ){

			add_action( 'woocommerce_init', function(){

				// CREATE SESSION IF ITS NOT ALREADY THERE. WE NEED IT IN ORDER TO SAVE COUNTRY SELECTION
				if( ! WC()->session->has_session() ){
					WC()->session->set_customer_session_cookie(true);
				}

				// SET NEW VALUE FOR THE COUNTRY IF $_POST['bi-country'] IS THERE (USER MANUALLY SUBMITTED THE FORM WITH A NEW COUNTRY)
				if( ! empty( $GLOBALS['wcpbc_frontend'] ) && ! empty( $_POST['bi-country'] ) ){

					// IF USER SELECTED THE "INTERNATIONAL" COUNTRY...
					if( $_POST['bi-country'] == 'INT' ){

						// SET THE COUNTRY BY USER IP
						//$_POST['bi-country'] = $GLOBALS['wcpbc_frontend']->default_customer_country(null);

						// OR SET THE COUNTRY BY FIRST AVAILABLE IN ALLOWED COUNTRIES LIST
						foreach( WC()->countries->get_allowed_countries() as $key => $value ){

							if( $key != 'CA' && $key != 'US' ){

								$_POST['bi-country'] = $key;
								break;

							}

						}

					}

					// ENSURE THAT CART MUST BE EMPTY ON SWITCHING THE COUNTRIES
					WC()->cart->empty_cart();

					// ITS A SHAME WE CANT ACCESS THE CUSTOMER OBJECT DIRECTLY, LIKE THIS: $this->customer->set_country( $_POST['bi-country'] );
					// SO BECAUSE WCPBC PLUGIN ONLY ACCEPTS $_POST['country'] AS COUNTRY, GIVE IT TO HIM.
					$_POST['country'] = $_POST['bi-country'];
					$GLOBALS['wcpbc_frontend']->checkout_country_update(null);
					unset( $_POST['country'] );

					// WHEN WE ARE CHANGING THE COUNTRY IN WCPBC PLUGIN, WE MUST DO THE SAME IN WOOCOMMERCE
					WC()->customer->set_country( $_POST['bi-country'] );
					WC()->customer->set_shipping_country( $_POST['bi-country'] );

					// ADD COOKIE TO REMEMBER THE VISITOR's CHOICE FROM THE LANDING PAGE COUNTRY SELECTOR POPUP
					if( ! isset( $_COOKIE['bi-initial-country'] ) ){
						setcookie( 'bi-initial-country', $_POST['bi-country'], (time()+60*60*24*365*5), '/' );
						$_COOKIE['bi-initial-country'] = $_POST['bi-country'];
					}

				}

			}, 200);

			// ADD SCRIPT AND STYLE TO PAGE OUTPUT
			add_action( 'wp_enqueue_scripts', function(){

			    $plugin_url = plugins_url( '', __FILE__ );

			    wp_enqueue_style( 'bi-prices-by-country-style-fancybox', "$plugin_url/fancybox/jquery.fancybox.css" );
			    wp_enqueue_style( 'bi-prices-by-country-style', "$plugin_url/style.css" );

			    wp_enqueue_script( 'bi-prices-by-country-script-fancybox', "$plugin_url/fancybox/jquery.fancybox.js", array( 'jquery' ), false, true );
			    wp_enqueue_script( 'bi-prices-by-country-script', "$plugin_url/script.js", array( 'jquery' ), false, true );

			});

			// ADD HTML ELEMENTS TO PAGE OUTPUT
			add_action( 'wp_footer', function(){ require_once 'html-output.php'; });

			//
			add_action( 'woocommerce_before_checkout_billing_form', 'bi_woocommerce_before_checkout_billing_form');
			add_action( 'woocommerce_after_checkout_billing_form', 'bi_woocommerce_before_checkout_billing_form');
			function bi_woocommerce_before_checkout_billing_form(){

				static $allowed_countries;
				static $current_country;
				static $already_called = false;

				if( is_null( $allowed_countries ) )
					$allowed_countries = WC()->countries->get_allowed_countries();

				if( is_null( $current_country ) )
					$current_country = WC()->customer->get_country();

				if( ! $already_called ){

					$already_called = true;

					if( $current_country != 'CA' && $current_country != 'US' )
						unset( WC()->countries->countries['CA'], WC()->countries->countries['US'] );
					else
						WC()->countries->countries = array( $current_country => WC()->countries->countries[$current_country] );

				}
				else
					WC()->countries->countries = $allowed_countries;

			}

		}

	}, 11);

Hi,

Firstly, great plugin oscargare. I developed a country selector which you can find here: https://strikt.ca

What I am missing, is that customer object should be set as PUBLIC. I want to alter it but there is no way because you set it to protected. Please include that in next version. WC also included customer object as public. I want to be able to do something like this:
$GLOBALS['wcpbc_frontend']->customer->set_country('NEW_COUNTRY');
