在美国结婚需要哪些程序？

题主可以去这儿仔细看看Marriage LicensesLas Vegas就是Clark County下所属的城市。=================================================For non U.S. citizens, some foreign countries require a copy of the marriage license and/or an apostille to register a marriage. It is suggested that non U.S. citizens check with their local officials for special documents needed to ensure their marriage is recognized in their country.If your home government authorities require a copy of the marriage license, you may want to consider purchasing a certified copy of the Affidavit of Issuance of Marriage License when you come to the Marriage License Bureau. This document contains information not listed on the marriage certificate such as parent's names and parent's places of birth. Because we do not offer online ordering of documents, it is easier to purchase the affidavit when you are at the Marriage Bureau instead of waiting until you return home.Apostilles (Authentication of Signatures) may be required to register and finalize a marriage in a foreign country. Information regarding apostilles can be found under the Licensing Center section on the website of the Nevada Secretary of State.我的理解是并不是你拿着美国结婚的license去其他大部分国家都可以的，不同的国家可能有不同的政策，也许 是直接承认的，也许需要一些文件证明，这些需要你自己向民政部门了解。据我在网上粗略的搜索了一下，国内要承认美国的婚姻关系是需要公证的。首先由美国公证对美国结婚证进行公证，然后由州州务卿（the Secretary of the State）认证（部分州要求先向County Clerk申请认证，再由州务卿认证，这个取决于每个州的法律），最后送 驻美使馆认证。另外对造成的误会表示歉意。祝你们幸福！
