It is recommended to maintain the H-1, H-4, L-1, L-2, etc., statuses because it provides an additional layer of protection in case of any government errors or complications with the I-485 situation. If, for any reason, the government mistakenly or intentionally targets your I-485 application, having an H-1B to fall back on can be advantageous. The H-1B status remains intact and offers continued benefits. 

On the other hand, the EAD (Employment Authorization Document), unlike H-1B, grants you the freedom to choose whether to work, not work, work multiple jobs, or even start your own business. However, there are certain limitations to consider. Interestingly, the derivative beneficiary, which refers to your spouse, may have more rights under the EAD compared to your own. It's important to exercise caution and be mindful of these distinctions.

If you are convicted, which implies involvement in a criminal case, you will be unable to leave the U.S. without serving your sentence. If you receive a jail term of six months, one year, or five years (or any other duration), you must complete that period before departing. The timeline for your departure depends on the current status of your case. It is not advisable to stay in the U.S. illegally, considering that you are already facing the worst outcome—a permanent ban from entering the U.S. Overstaying by an additional six or eight months would result in an additional bar of three to five years on top of the existing permanent ban of three to ten years. As for your assets, unless there is some form of asset forfeiture, you can take your money and sell your house before leaving.
