This is a challenging question. Typically, an applicant will wait for the results of a K1 visa application before travelling to the United States. In some cases, applicants have been able to travel if they had an existing U.S. tourist visa already approved or were from a Visa Waiver Program country.
However, there are also cases where applicants try to enter the United States and are stopped at the border. U.S. officials then see an in-progress green card or fiancée visa application and ask questions, request evidence, and possibly return applicants to their home countries.
The bottom line is that there’s no rule against travelling to the United States while waiting for your visa outcomes. But our experience and the experience of our customers is that U.S. officials are going to assume that you’re trying to immigrate to the United States because you have a pending green card or fiancée visa.
If you use a temporary visa, like a tourist visa, U.S. officials might assume that you’re just trying to short-cut the process and you’re going to stay and not honor the tourist visa by leaving within the 90 days.The wait is difficult. It is hard being apart from your loved one, but it’s best just to wait it out.
