Hello garazariepu,

Yes it is possible to achieve your requirement. 

You can add "Facebook Like Me First" widget in your form which will ensure that your user like your FaceBook page before they can submit the form. Please take a look at the widget here:  http://widgets.jotform.com/widget/facebook_like_me_first

Hope this helps.

Do get back to us if you have any questions.

Thank you!
