Adding new user contact fields also in user-new.php in wordpress

I have already found a code the let me add new user contact fields, the problem is that I can just edit these fields, but when I’m creating a new user I dont see these fields immediatly, my desire is having these fields from the start in the page user.new.php, and of course the content should “stick”

//adding contact fields to user profile 

function extra_contact_info($contactmethods) {

$contactmethods['fax'] = 'Fax';
$contactmethods['address'] = 'Indirizzo';
$contactmethods['postalcode'] = 'Codice Postale';
$contactmethods['town'] = 'Comune';
$contactmethods['country'] = 'Paese';
$contactmethods['taxcode'] = 'Codice fiscale';

return $contactmethods;

}
add_filter(‘user_contactmethods’, ‘extra_contact_info’);
