變更

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 /blockquote><blockquotebr />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>

*重新填DS-160，不改预约，然后 在打指纹 在ASC拍照 的时候让工作人员换DS-160
