No. Uzbekistan doesn't ask visitors to fill in an online arrival form (also called an entry form, immigration card or landing card) before they travel. Some nationalities need an eVisa. Registration within 3 days, usually by the hotel.
Do I still need a visa for Uzbekistan?
An arrival form is not a visa. Whether you need a visa or an electronic travel authorization depends on your nationality, so check Uzbekistan's official immigration website or your own government's travel advice.
