Automatically deleting related rows in Laravel

I have two table with relation, defined in model and migration but when I delete the parent data the child do not delete automatically

User model

class User extends Authenticatable implements MustVerifyEmail
{
    use Notifiable;
    use Friendable;
    use HasApiTokens;

    public function userstatus()
    {
        return $this->hasOne(UserStatus::class);
    }
}

UserStatus model

class UserStatus extends Model
{
    public function user()
    {
        return $this->belongsToOne(User::class);
    }

}

User migration:

class CreateUsersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->increments('id');
            $table->string('first');
            $table->string('last');
            $table->string('description')->nullable();
            $table->string('phone');
            $table->string('question');
            $table->string('answer');
            $table->string('email')->unique();
            $table->string('country');
            $table->string('city');
            $table->timestamp('email_verified_at')->nullable();
            $table->timestamp('verified')->nullable();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('users');
    }
}

UserStatus migration:

class CreateUserStatusesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('user_statuses', function (Blueprint $table) {
            $table->increments('id');
            $table->foreignId('user_id')->constrained('users')->onDelete('cascade')->onUpdate('cascade');
            $table->string('status')->default('InActive');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('userstatuses');
    }
}

and I also tried using old ways on migration not working. There are a lot of relations in user and I can’t delete them one by one each time so it needs to delete automatically.
