The original idea behind setting up a “global office” isn’t intended for guiding students on other aspects of immigration - their primary role is that of maintaining and updating international students’ records in SEVIS, period. A school such as yours may decide to bring in USCIS officials to brief international students - most colleges do not offer that service.
It is therefore unreasonable IMO to expect some college based Global office to be “reliable when it comes to other aspects of immigration” simply because international students “pay triple the cost of tuition fees compared to local students” - the schools do not owe international students that service because of the amount of money they pay. Local students attending public schools in their States of residence pay significantly less than international students because their parents presumably pay taxes, part of which is used in funding the schools international students are benefitting from by attending. A local student who opts to attend a private institution is expected to pay the same amount of tuition fee as an international student, as those private institutions are self funded (they do not benefit from government funding derived from tax payers).
I realize this conversation is digressing from the purpose and intent of this thread, but I feel it is important to address certain misconceptions being expressed on the thread.
