ow do I prove ties to the home country if I am not working nor studying when traveling to the USA on visa waiver program?

All visitors to the United States under visitors visas or visa waiver program should have nonimmigrant intent – that is, that they should not intend to stay in the country past their period of visit. In the event that a Customs and Border Protection (CBP) officer has doubts on the score, it is the burden of the entrant to show sufficient ties to the home country to convince the officer that he or she will return. Any of the steps that you have outlined to show your nonimmigrant intent would be okay along with items such as bank account or personal or real property in the Czech Republic. Even without such proof, most CBP officers would not give you a hard time if you have not been abusive of the visa waiver program in the past. Also you may be lucky enough to be in the inspection line of an officer who is kind to visitors around Christmas time. In answer to your question of the repercussions if you travel to the US and are deported, you would be barred for five years if such occurred upon entry at the port of entry and for 10 years if you were admitted to the country, got yourself into trouble with the Department of Homeland Security later, and were ordered deported by an immigration court. Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
