Answer 1

You can try with mutators :

class User extends Model
{
    public function setNameAttribute($value)
    {
        $student= Student::where('user_id', $this->id)->first() if id is not key in Student
        $student->name = $value;
        $student->save();
        $this->attributes['first_name'] = $value;
    }
}

Answer 2

You should use the observers. When a User is updated, the Student will automatically also being updated.
