How to apply for a tourist visa to the United States? Which company is better?

It mainly depends on the visa knowledge of your visa officer, the rich experience of visa application and the American society and culture you need to know. Let me talk about the relevant elements involved, and you can find them yourself according to these principles.

1 If we talk about globalization and internationalization, it is obviously inseparable from the United States. Therefore, the United States has detailed visa categories and regulations for traveling to the United States or conducting business and academic activities. People who help you should have this knowledge.

Have rich experience in visa consultation. The first is theory, and the second is practical experience. My family once met people who refused to sign three times, and other families couldn't say it, but then they found me after reading my article. After detailed analysis, I made sure that I could take his case (I didn't take everyone's case). Then communicate with him to help him determine the visa plan and visa ideas, then prepare visa materials according to the plan and answer visa interview questions according to the visa ideas. After many patient and serious instructions, I finally got the visa.

Familiar with American society and culture. Familiar with American society and culture, so as to understand American thinking and answer questions that Americans can understand. Many people are refused visas because although everyone speaks Chinese or English, they have different cultural backgrounds and different thinking. The way you said it was not understood by others, and finally you were refused a visa. It is safe to find a professional organization. I recommend trying it on the "problem solving network", which may solve your problem.
