Jerryfan5,
Nothing technical about it - a visit to the USA is allowed while the immigration process is underway. As for any visit, the visitor must show that their visit will be of limited duration and after their purpose is accomplished they will leave.

Hmm...Has anyone tried traveling to the US (for <1week) while applying for the green card? I know it's not technically allowed, but if one is only visiting temporarily and clearly prove ties to his/her home country, is that OK?
