Dear gods, my girlfriend and I are both doctoral students at Beijing Institute of Technology. She went to America for an exchange last year (no degree), and I want to see her.

I found this online. I understand how you feel. I hope it will help you a little.

B2 You can apply for a B-2 visa for sightseeing, entertainment, visiting relatives and friends, seeking medical treatment, attending conferences, attending exhibitions and handling personal affairs in the United States. B-2 tourist visas are valid for 3 months, 1 year, 3 years, 5 years, 10 year and permanently, and the number of entry times is also valid for single entry and multiple entry. American embassies and consulates in different countries or regions, or different consuls in the same consulate, have great discretion over the validity or number of entry visas. At present, it is easier for Hong Kong and Taiwan residents to apply for a B-2 visa with multiple entry for 1 ~ 5 years, while it is easier for Chinese mainland residents to apply for a B-2 visa with multiple entry for three months to 1 year.

The difficulty of applying for a B-2 visa depends on different countries and situations. The United States grants visa-free treatment to tourists from some countries, such as Austria, Belgium, Denmark, Finland, France, Germany, Italy, Japan, New Zealand, Spain, Sweden and Britain. However, at present, nationals of Chinese mainland, Hongkong, Taiwan Province and Singapore do not enjoy visa-free B-2.

In areas where it is difficult to apply for a B visa, such as Chinese mainland, generally speaking, the main factors considered by visa consuls are the necessity of the applicant going to the United States and whether the applicant has an immigration tendency. Financial ability is an important consideration in theory, but it is often not the most important in visa cases. Therefore, applicants should focus on how to provide strong materials to prove that it is extremely necessary to go to the United States and will return to China on time.

To apply for a B-2 visa, the following documents and supporting materials shall be submitted:

Basic materials—

0f- 156 table

draw

Invitation letter or reasons for going to the United States.

Passports valid for more than 6 months,

Supplementary materials-

(1) Economic guarantee issued by American relatives and friends.

(2) the applicant's economic proof (such as bank deposit certificate, traveler's checks, etc.). ),

(3) Round-trip air tickets.

(4) Explanatory materials, such as real estate license, owner's certificate and work certificate.

B-2 visa application is refused and cannot be appealed.

Entry with a B-2 visa, American port immigration officers generally don't ask about the time limit. If you ask how long you will stay in the United States, the holder can also ask directly for six months.

The procedures and documents for applying for extension of B-2 visa are basically the same as those for B- 1 visa. The following documents are required to apply for B-2 visa extension:

(1)I-539 table;

(2)I-94 entry record card;

(3) the applicant's financial (bank) certificate or economic guarantee issued by relatives and friends;

(4) If there are family members, submit proof of relationship, such as marriage certificate and birth certificate;

(5) an application letter written by the inviter, relatives, friends or myself, which aims to explain the reasons for the extension and has sufficient economic ability to maintain the expenses in the United States;

(6) application fee.
