PHP header location redirect loop

Question

I found this php geo-redirect script here

Here is the code:

<?php
require_once('geoplugin.class.php');
$geoplugin = new geoPlugin();
$geoplugin->locate();
// create a variable for the country code
$var_country_code = $geoplugin->countryCode;
// redirect based on country code:
if ($var_country_code == "US") {
header('Location: http://domain.com');
}
else if ($var_country_code == "NL") {
header('Location: http://domain.com/nl');
}
else if ($var_country_code == "FR") {
header('Location: http://domain.com/fr');
}
else {
header('Location: http://domain.com/int');
}
?>

I placed this code at the very beginning of my index.php.

The problem which I am getting and trying to solve is that when my IP is US based redirect script should redirect to itself and stay on home page. Instead I am getting some redirect loop and page doesn't load properly.

If location is US, then no need to redirect:

<?php
require_once('geoplugin.class.php');
$geoplugin = new geoPlugin();
$geoplugin->locate();
// create a variable for the country code
$var_country_code = $geoplugin->countryCode;
// redirect based on country code:
if ($var_country_code == "US") {
   //header('Location: http://domain.com');
}
else if ($var_country_code == "NL") {
header('Location: http://domain.com/nl');
}
else if ($var_country_code == "FR") {
header('Location: http://domain.com/fr');
}
else {
header('Location: http://domain.com/int');
}
?>
