I would like to ask, I have submitted an application for a U.S. tourist visa on the website. Do I just need to print the confirmation letter?

Yes, only the confirmation letter is required for Form DS-160. However, it is best to back up the detailed application form.

Of course, you can apply for a stay of 3 months, but I suggest that it is better to say that you plan to go for 1 month. If the visa is approved, you can stay as long as you want, as long as you come back within the validity period.

Regarding receiving friends in the United States, if you only have a tourist visa, then the friend does not need to provide anything. If the visa officer asks if I have relatives or friends outside the United States, I can say that there are friends outside the United States who really hope that I can go out and can be my tour guide.

The required documents are as follows:

1. Valid passport: If your passport will expire within six months of your expected arrival date in the United States, or is damaged, or the passport There are no more blank visa issuance pages. Please apply for a new passport before coming for your interview.

2. DS-160 form confirmation page. Please indicate your name's code, Chinese name, Chinese home address, company name and address on it. Please print your form confirmation page vertically on A4 paper. Please bring the printed confirmation page of the DS-160 form to the interview. Do not use the faxed confirmation page.

3. One photo: A 2-inch x 2-inch (51 mm x 51 mm) square color frontal photo with a white background taken within 6 months. Please use clear tape to attach your photo to your passport cover.

4. Original receipt of visa application fee: You can pay the visa application fee of RMB 966 at any branch of CITIC Bank in China (effective from June 4, 2010). Please glue or tape the receipt to the bottom half of the confirmation page.

5. Evidence that can explain why you will definitely return to China: Provide financial, social, family or other documents that are binding on you to help you prove your intention to return to China after a short stay in the United States . Due to different personal circumstances, the evidence that applicants should produce will also vary. The following documents can help the visa officer evaluate whether you intend to return to China: household register, ID card, employment certificate, pay stub that objectively reflects your monthly income, bankbook with normal and regular deposit and withdrawal records, etc.
