Do I have to have immediate family members to apply for immigration to the United States or to visit relatives?

Yes, it's not a parallel system. It doesn't matter. Even if there are immediate family members abroad, it is recommended to apply for a tourist visa, because visiting relatives requires reviewing the information of both domestic and foreign parties, while tourism only reviews the information of domestic applicants.

1. If you want to visit relatives, you must be an immediate family member before you can apply for a visit visa, and you must have good information at home and abroad before you can pass. Tourism application is relatively simple, as long as the domestic applicants have good information, they can pass.

2. If the applicant's information is poor and there are relatives abroad, it seems that there are still people abroad who can meet, and the immigration tendency is more serious. It is easier to refuse a visa; If the visa applicant's information is good, but if the information of foreign relatives is not good, it will also lead to visa refusal. For example, whether the status of foreign relatives is legal, whether their jobs are stable, whether they have a stable residence, whether they have enough assets and whether they pay enough taxes will all affect the visa pass rate.

To sum up, if the applicant has good information and foreign relatives, it is icing on the cake, and the customer information is good, so naturally there are foreign relatives; If the applicant has poor information and relatives abroad, it will be even worse.

Moreover, the types of visas applied for travel are exactly the same as those applied for visiting relatives. They are all B 1/B2 visas, B 1 is for business and B2 is for visiting relatives. That is to say, even if you travel, you can go to business and visit relatives. Because you got two kinds of visas at the same time: a visiting visa and a business visa. And the time spent in the United States is the same every time, up to half a year. It doesn't affect your visiting relatives at all.
