Travel while adjustment of status is pending is generally only allowed if you have a valid advance parole document. Leaving the U.S. without advance parole can be considered abandonment of your application. Even with advance parole, reentry is not guaranteed and is subject to inspection at the border.

Before traveling, it is important to confirm that no other issues exist, such as unlawful presence or prior immigration violations, that could trigger problems upon return. Short, well-documented trips are usually safer. When in doubt, consulting a professional before travel can help prevent serious consequences.
