Is it permissible for the suitor to visit his fiancée once every two months in her father's house, in the presence of a mahram, without uttering emotional phrases, knowing that he cannot marry for two years due to his studies?

If the suitor and the prospective bride are pleased with each other, the default is for them to cease communication until the marriage contract. Visits are permissible only when necessary, provided there is no enjoyment of each other or display of charms. Frequent visits open doors for Satan and increase attachment. It is preferable not to prolong the engagement period.
