I see two substantial issues based upon the information provided. The first is you intend to work in the United States after entry with a B-2 non-immigrant visa. You are not allowed to work in the United States without authorization regardless of whether you have an old social security number. Unauthorized employment at the very least can be an adverse factor and can be a bar to future admission. It may not directly impact a petition filed by a spouse who is a U.S. citizen, but if you do not marry it can have serious consequences to future admission.
You have also mentioned your intention to marry next month. You cannot use a B-2 non-immigrant visa to enter the United States with the intent to permanently immigrate. This is considered i"immigrant intent" and can result in a finding that you committed fraud/misrepresentation upon your entry. This can lead to a permanent bar to admission that can only be waived if you can establish a qualifying relative will suffer extreme hardship. If you wish to marry in the United States and seek permanent residence, you are best off either marrying and returning to your native country for consular processing of the immigrant visa or entering with a fiance visa.
It would be in violation of status for you to work. Unlawful employment is not a bar to adjustment of status.
The above is intended only as general information, and does not constitute legal advice. You must speak with an attorney to discuss your individual case.
