<select class="form-control" name="nation_id" id="nation_id">
          <option value="">Select nation</option>
           @foreach($nations as $nation) 
            <option value="{{ $nation->nation_id }}">{{ $nation->nation_name }}  </option>
          @endforeach
</select>

<select class="form-control" name="teacher" id="teacher">
</select>

now the ajax code:

<script type="text/javascript">
$('#nation_id).change(function(){
    var nid = $(this).val();
    if(nid){
        $.ajax({
           type:"get",
           url:"{{url('/getTeacher)}}/"+nid,
           success:function(res)
           {       
                if(res)
                {
                    $("#teacher").empty();
                    $("#state").append('<option>Select Teacher</option>');
                    $.each(res,function(key,value){
                        $("#teacher").append('<option value="'+key+'">'+value+'</option>');
                    });
                }
           }

        });
        }
});
</script>

now in controller file;

public function getTeacher($id)
{
    $states = DB::table("teachers")
                ->where("nation_id",$id)
                ->pluck("teacher_name","teacher_id");
    return response()->json($teachers);    
}

And last for route file:

Route::get('/getTeacher/{id}','TeachersController@getTeacher');

Hope this will work..
Good Luck...

Create a route for your method which will fetch all the nations-

Route::get('nations-list', 'YourController@method');

Create a method in your controller for the above route-

public function method()
{
    $nations = Nation::all()->pluck('nation', 'id');

    return response()->json($nations)
}

Add a select box like this in your HTML-

<select id="nation_id" name="nation_id"></select>

If you want to auto select the option based on a variable then you can do this-

<input type="hidden" name="teacher_nation_id" id="teacher_nation_id" value="{{ $teacher->nation_id ?? '' }}">

And then add this script in your HTML to fetch the nation list on page load-

<script>
$(document).ready(function($){
    $.get('nations-list', function(data) {
        let teacher_nation_id = $('#teacher_nation_id').val();
        let nations = $('#nation_id');
        nations.empty();

        $.each(data, function(key, value) {
            nations.append("<option value='"+ key +"'>" + value + "</option>");
        });

        nations.val(teacher_nation_id); // This will select the default value
    });
});
</script>
