申根多次往返签证声明？
题主好，首先我并不清楚你为何需要这份声明； 其次， 我也找不到任何官方的， 正式的文件中提到了这种声明. (有找到的话欢迎赐教) 最后， 关于多次入境申根签， 可参考德意志银行给出的说明（德意志银行是德国政府指定的签证代理机构）： DBA GLOBAL VISAS VISA REQUIREMENTS FOR TRAVEL TO THE EUROPEAN UNION AND SWITZERLAND (10-9-2015)： You need a visa to enter the Schengen Area， if you want to： Stay more than 90 days in any 6 month period while in Europe; or Do work for pay， either as an employee or self-employed person， within the area. To qualify for this type of visa you must be coming from another country and hold employment in one of several specific professions required by European Union countries. If your stay is less than three months or you are not working， you don't normally require immigration permission， but some EU nations do have restrictions on visitors who want to remain longer. If so， check with your embassy before traveling： Some countries offer visas upon arrival at airports that allow tourists to visit without first obtaining approval through embassies abroad. But each nation has its own requirements and some have strict enforcement policies which could cause problems for travelers later． For example Spain has been known to refuse entry to vacationers who appear to have overstayed their original tourist visas． Similarly Germany recently began fining citizens of certain non-EU countries up to $379 for unauthorized stays exceeding four days．
Therefore， I wouldn’t worry about making such statements unless you know there was something amiss concerning your travel plans/status. Otherwise， just enjoy your travels！
Have fun exploring new places！
