美国配偶签证要等多久？
我是去年10月份递交的表格，今年8月拿到通知去面试，前后等了九个月的时间，不过中间由于我换工作所以耽误了几个月的时间 下面是官方给出的时间表：
Step 1： Filing the Petition to Immigrate with USCIS： This petition is filed after your marriage has been legally recognized by entering into it in a country that recognizes marriage between two people of different sexes. Once USCIS receives and accepts this filing， they will send out an Approval Notice that includes instructions about how to proceed.
Time frame： Up to six months， if you have all required documentation and file electronically. If you do not meet these criteria，the time frame may be substantially longer because additional information must be requested from you and then processed before we can make any decision on the form you’ve submitted.
Step 2： Interview at a USCIS Application Support Center (ASC) or International Field Office（IFO）： After receiving approval of our Form I-765 or I-131 in Step One above， you would get invited for an interview by either ASCs or IFOs in your home state or local area。This step takes place within six weeks of being approved and generally occurs one year following receipt of the request for evidence(RFE)，if applicable，or the date of filing of the petition， whichever comes first。It should also take approximately three hours for each party involved in the process： both spouses need to come along．The cost depends on which type of appointment is sought as well as whether the applicant resides inside or outside of the U.S. The USCIS website offers more details on fees and payment options.

While this requires some paperwork beforehand and an initial in-person visit to gather other documents，it eliminates the hassle of getting across multiple borders and having to go through customs when only going in for an interview.
