第18届全美力学大会已经在美国国务院网站注册，建议持中国护照的参会代表尽快开始申请赴美签证（至少提前4个月）。
Information on visas can be found at the U S Department of State Business Visa Center website and the International Visitors Office website of the U S National Committee on Theoretical and Applied Mechanics.
If you require a visa to enter the US, we strongly encourage you to apply for their visas as early as possible — at least three to four months before the meeting is recommended. Some consulates may have backlogs in scheduling visa interviews. Therefore, applicants should first consult the U.S. Department of State’s visa appointment and processing wait times website.
If you experience significant visa delays, we encourage you to fill out this visa survey. This will allow your request to be brought to the attention of the State Department.
