This is to ensure that you will return home before your tourist status expires. Here are some examples of documents that can help demonstrate strong ties to your home country:
It is also generally a good idea to provide copies of your bank statements, credit card statements showing healthy spending limits, or other proof that you will be able to support yourself financially during your visit to the United States.

Visiting the United States while you have a pending I-130 petition (the first step in obtaining a marriage-based green card) is a delicate balance. You clearly intend to move to the United States permanently, once you obtain your green card. But at this point, you are required to convince the consular officer or CBP agent that you will not do it yet.
This can be difficult to do if you have already quit your job and sold your property in your home country. That is why many people choose to visit the United States before doing any of those things.
It is important to present strong evidence that you will be returning to your home country after your short visit, although there is still always a risk, as entry is not guaranteed.
If you do not have a pending I-130 petition, that is, if you have not started the process of the marriage green card, you will not have to worry about the aforementioned balance (which clearly intends to settle in the United States soon) .
You may still face additional scrutiny when applying for a tourist visa or arriving in the United States because the consular officer or CBP agent may suspect that you intend to bypass the I-130 process by means of enter with a tourist visa and then apply for a matrimonial residence card (known as “adjustment of status”) once you are in the United States.
If you do not have an immediate plan to settle in the United States, you must be clear on this point in your visa application. Some additional things you may want to check include:
Again, you should never lie about the fact that your spouse is a US citizen or green card holder, because lying could jeopardize your ability to obtain a green card in the future.
