Is a travel agency reliable in processing non-immigrant US visas?

There is nothing to be afraid of when the United States refuses a visa. Sometimes the mood of the visa officer determines everything. We have helped students who were refused student visas 6 times to overturn their cases. The weaknesses in your application conditions are likely to be amplified by your poor performance during the interview. If the visa officer is interested in you, two sentences can solve the problem.

Many of our students who are not good at English have failed once when they went to study abroad for interviews, because they really didn’t get used to it the first time, but they will be much better the second time. Don’t be nervous.

You can provide more official invitation letters and itineraries. If your previous work resume is good, you can mention it appropriately and explain why you changed jobs, which can explain some of your questions. It is also possible to find a guarantor as suggested by other friends. You also need to find some proof that you will definitely stay in the country. If you don't have one, you can just say that you need to take care of your parents or something.

In addition, it is not recommended that you change the purpose of your application, because the US consulate has internal records. Last time you said you were going for business, and this time you said you were going for tourism, this will definitely make the visa officer think there is something wrong. You have to prepare the materials carefully for the reason for rejection. There is still hope. It mainly depends on your communication performance and the mood of the visa officer. If you are good, it will be over in two sentences. If you are in a bad mood, you may be rejected in one sentence.
