All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallaahu ʻalayhi wa sallam, is His slave and Messenger.
If the chat between you and this young man is within the limits of Shariah etiquette and it is done in a general group such that Fitnah (temptation) is not feared, then there is no harm in resorting to it – Allah willing. It should be noted, though, that this is not the best way to know about the religiosity and manners of this young man. Rather, it is better to ask trustworthy people who know him, following the example of the female Companion who consulted the Prophet, sallallaahu ʻalayhi wa sallam, regarding her suitors. It was narrated that Faatimah bint Qays said to the Prophet, sallallaahu ʻalayhi wa sallam, “Mua'awiyah ibn Abi Sufyaan and Abu Jahm both proposed to marry me.” The Messenger of Allah, sallallaahu ʻalayhi wa sallam, said, “As for Abu Jahm, he never puts down his stick from his shoulder (this may mean either that he travels a lot, or that he habitually beats his wives), and as for Muʻaawiyah, he is a poor man with no money. Marry Usaamah ibn Zayd!” She did not like it, so then he said, “Marry Usaamah.” So she married him, and Allah blessed them and she was envied (by others). [Muslim]
If trustworthy people praised his religiosity and manners, then accept his marriage proposal and perform the Istikhaarah (guidance-seeking) prayer to seek the help of Allah in this matter. If marrying him is good for you, then Allah will facilitate it; otherwise, He will turn him away from you. Refer to fatwa 81434 about the Istikhaarah prayer.
Differences in academic degrees and the like do not prevent accepting the marriage proposal of a suitor in the Shariah. If your parents reject the proposal, try to convince them. If they responded to you, all praise be to Allah. If they refused him without a valid reason, you may refer the case to the Islamic center in your country or the like.
If your parents' intention is not to harm you with their refusal, then be patient until Allah, the Exalted, blesses you with another righteous suitor, especially given that parents love their children and seek their best interests.
As for informing your parents of your wish to marry this man, we believe that it is simple; you can ask his sister, for instance, to visit your mother and inform her that her brother wishes to propose or the like of proper behavior that would eliminate suspicions.
Allah knows best.
