While the I-526 petition is pending you may leave the U.S. and you can return to the U.S. with a visitors visa. When you return with a visitors visa you have to intend only to stay in the U.S. for a temporary period of time and then return to your home country. You can not use the visitors visa to enter the U.S., wait in the U.S.until your I-526 petition is approved, and then apply for conditional permanent residency and adjust here in the U.S. Under the right circumstances you may have a choice in applying for residency while in theU.S.or applying directly for a residency visa through the U.S.consulate.
This could have an effect on your plans to obtain the Conditional Permanent Residency. At the time of filing the I-526, you will indicate that you either wish to be processed through the consulate in your home country or adjust status in the US. Depending on your current US Immigration status, you may be able to extend your period of stay. We recommend retaining experienced US immigration counsel, like the attorneys at our law firm, to help you arrange a timeline for your immigration processes and goals.
