Well first you have to code to detect user location this following code will help you i am using API

<?php
function get_client_ip() {
    $ipaddress = '';
    if (isset($_SERVER['HTTP_CLIENT_IP']))
        $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
    else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
        $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
    else if(isset($_SERVER['HTTP_X_FORWARDED']))
        $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
    else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
        $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
    else if(isset($_SERVER['HTTP_FORWARDED']))
        $ipaddress = $_SERVER['HTTP_FORWARDED'];
    else if(isset($_SERVER['REMOTE_ADDR']))
        $ipaddress = $_SERVER['REMOTE_ADDR'];
    else
        $ipaddress = 'UNKNOWN';
    return $ipaddress;
}

$return = array();
$ip = get_client_ip();
if (strpos($ip, 'UNKNOWN') !== TRUE)
{
$return = json_decode(file_get_contents('http://geoip.nekudo.com/api/'.$ip));
$code = $return->country->code;
if (strpos($code, 'US') !== FALSE)
{   //redirect user to US Page    }
?>

you can use this code in header.php this example is for US visitors for Denmark you have to just replace US country code with Denmark
