Yes, you can switch to a highly skilled migrant visa after your Netherlands Orientation Permit expires. To do so, you will be required to find a Dutch employer who is willing to sponsor your permit before the expiration of your Orientation permit. The new Dutch employer can apply for a Highly Skilled Migrant (HSM) residence permit on your behalf, or apply for a single permit for residence and work, if your new job does not meet the requirements for an HSM visa.
