At the end of the last working day of the 90-day stay, a visitor may apply to stay in an EU country for a longer period if his country of origin has a current formal agreement with that Member State. Most bilateral agreements allow travellers to spend an extra 3 months without a visa. Citizens of each of the 60 eligible countries must complete the application online and benefit from an authorized exemption from the ETIAS visa requirement before entering one of the Schengen countries. The program will be very similar to the exemption from the visa requirement of the ESTA, which travels before many nationalities before traveling to the United States. Schengen visas can be issued by any Member State of the Schengen Area. Travellers should contact the embassy or consulate of the country they wish to visit. For travellers to several Schengen countries, travellers must apply to the embassy or consulate of their main destination.  If it is not possible to determine the main destination, the traveller should apply for the visa at the embassy of the Schengen Member State from the first entry.   Often, external service providers are mandated by certain diplomatic missions to process, withdraw and return visa applications. In this sense, changes to bilateral visa waiver agreements can only be made by both parties.
In other words, the current bilateral agreements between an EU Member State and a third country, which provide more favourable entry conditions for both countries, are subject to changes, observations and/or improvements, provided that the two sides are coordinated in their decision. Some third-country nationals are allowed to stay more than 90 days in the Schengen area without having to apply for a long-stay visa. For example, France does not require nationals of European micro-states to apply for an extended residence visa.  Nationals of countries (such as Australia, Canada, Malaysia, New Zealand, Singapore and the United States) who had visa-free agreements with Schengen states prior to the implementation of the Schengen Agreement may stay up to 90 days without a long-stay visa in each of these Schengen states (see “Rules applicable to Schedule II nationals”). To successfully apply for an ETIAS visa exemption, you need a valid passport, a credit or debit card and an e-mail account. These are the main ETIAS requirements that each applicant must have. Without the correct travel document, the applicant could be denied entry to the Schengen area. Access to nationals of Albania, Bosnia and Herzegovina, Georgia, Northern Macedonia, Moldova, Montenegro, Serbia and Ukraine applies only to biometric passport holders who are subject to visa-free travel. Access to the visa exemption does not apply to passport holders issued by the Serbian Coordination Directorate that issues Serbian passports in Kosovo.
