按官方说法,DS-160上的城市不重要,换城市也不需要重填。参见国务院官网的DS-160 FAQ https://travel.state.gov/content/travel/en/us-visas/visa-information-resources/forms/ds-160-online-nonimmigrant-visa-application/ds-160-faqs.html
<blockquote>'''What happens to my DS-160 if I select a U.S. Embassy or Consulate where I will be applying for my visa, but end up making an interview appointment instead at another U.S. Embassy or Consulate?''' <br /> <br /> The Embassy or Consulate at which you actually apply should be able to access your form using the barcode on your DS-160 confirmation page, which you must bring to the visa interview. For example, a business traveler intends to apply for his visa at the U.S. Embassy in City X, so he selects City X as the location where he will submit his application when he completes his DS-160. He then has an urgent reason to travel to City Y on business. Because there is a U.S. Consulate in City Y, he schedules an appointment for a visa interview there, using the barcode from his completed DS-160 application for appointment scheduling. The U.S. Consulate in City Y is able to accept his DS-160 even though it lists the U.S. Embassy in City X as the location where he originally intended to submit his application.</blockquote>
虽说DS-160全球通用,但不建议跨国使用。不同国家有些小区别(比如墨西哥需要去ASC拍照),跨国使用可能会导致一些小问题。一国之内换城市,一般是没有问题的。一般 情况 以外, 出现意外 就是以下原因:
<blockquote>While it is technically possible for a DS-160 to be transferred from one post to another, the time that it takes to transfer the DS-160 is unpredictable; the transfer may impose additional burdens on posts; the transfer is complicated if the originally listed post recorded the applicant as a no-show; and a busy post (and applicants) may conclude it is far more efficient to work with a new application, than to wait for the DS-160 to transfer.</blockquote>
==修改DS-160信息==
如果是不重要的信息,比如 intended travel dates 之类的 ,不需要修改。
如果是重要信息,比如换了学校,有三个选择
*重新填DS-160,取消预约,修改账户里的DS-160号码,然后重新约(不需要重新缴费)
*在面试的时候把新信息告诉面试官,面试官手工帮你修改
在AILA提问DS160信息是否必须修改的时候,DOS回答是:The DS-160 applications are locked upon submission. Consular staff may enter remarks, but generally the original data remains as submitted. 然后又问换了新护照是否要改DS160,回答是:It is not necessary for the applicant to submit a new DS-160. Once the DS-160 is submitted, it can be unlocked by the consular officer for purposes of making certain changes, but the passport number in the CEAC cannot be changed. The applicant should be able to enter the consular section, but should be sure to bring both the new and old passports to the interview. The consular staff can enter remarks concerning the new passport information on the DS-160 and consular officers should be able to process the case in our adjudication systems using the new passport.
