Aftering marrying a U.S. citizen I re-entered the U.S. under a student visa, will this negatively affect my adjustment of status

Yours is a situation requiring careful preparation for your Adjustment Interview so that you can present your intentions and facts appropriately. A student visa is a temporary visa and your use of it would only have been proper if you intended to go to school and then return abroad when you finished school. Having married a US citizen could, arguably, make the intention to return abroad questionable in the eyes of a USCIS examiner. However, if you and your spouse were unsure where you would live after graduation or if your plans changed at some point after entry, you should have no problem with your Adjustment of Status. It is always important to remember that USCIS has much discretion in the Adjustment process so it is important to carefully prepare, especially when you have a potentially complicated issue such as this. If you had filed within 30 days of entry, there would have been a presumption that you intended to remain permanently when you used the student visa and that would have been evidence of visa fraud so at least you are beyond that hurdle. On the other hand, if you knew, when you entered as a student, that you were going to file for Permanent Residency, you may wish to consider filing the I-130 with a request for Consular Processing to avoid any allegation that your entry as a student was fraudulent. If you do not apply for Adjustment, you will have established that your intention was to go to school (which you did) and then to depart the US.
