Answer 1

Your Passport model don't belongToMany statuses, but hasManyThrough statuses.
Maybe your problem is here.
I think the line in your model Passport.php should be like this :
public function status()
{
return $this->hasManyThrough('App\Statuses',"passport_statuses","passport_id","statuses_id")->withTimestamps();
}
Check BelongToMany and HasMany documentation on laravel.com

Answer 2

class Passport extends Model
{
protected $fillable=[
'Full_Name',
'Date_of_Birth',
'Passport_Number',
'comments',
'Delivered_to_owner'
];
public function status()
{
return $this->belongsToMany('App\Statuses',"passport_statuses","passport_id","statuses_id")->withTimestamps();
}
}
class Statuses extends Model
{
protected $fillable=[
'Status_Name'
];
public function passport()
{
return $this->belongsToMany('App\Passport',"passport_statuses","statuses_id", "passport_id")->withTimestamps();
}
}
belongsToMany relation takes third argument foreign key of current Model table and 4th parameter foreighn key of related model table
of course your table has to be like this passport_statuses with with at least two columns statuses_id and passport_id.And in your example with created_at and updated_at timestamp columns

I was able to solve this by changing input('statuses') to input('Status_Name') in PassportController
$passport->status()->attach($request->input('Status_Name'));
