On the issue of American visa

The agent is to help you fill out the form. If you want to fill out the form yourself, you don't need an intermediary. And sometimes it is natural for the intermediary to fill it in for you blindly.

Log on to the website of the US Embassy and fill in the form DS 160 (electronic photo required). Print out

Online registration (ask the customer service of CITIC Bank on the website, they all know it), login, step by step operation, online banking payment (registration is required in CITIC Bank Financial Center), print payment confirmation page (sent to the email address filled in when registering), make an appointment interview, and print appointment confirmation page (sent to your email address with barcode).

Go to the embassy or consulate for an interview at the appointed time.

Required documents: passport, DS 160, payment confirmation page, reservation confirmation page (a little forgotten, it seems that the last two are one, just bring that barcode).

Try to provide: bank running water, real estate license, income certificate, deposit certificate, household registration book, marriage certificate provided by husband and wife, retirement certificate provided by retirees, some photos taken by people going abroad and some photos taken by husband and wife. If there is a detailed itinerary, print it out.
