Regarding EIN's it seems that many UK universities have US EINs. The student simply needs to request the EIN from the university, and the university will send the EIN or a 1098-T. Oxford and Durham both have EINs. It appears that UCL does as well, as it is published on one of their websites (https://www.ucl.ac.uk/research-services/generic-information/ucl-institutional-information), although I would have the student contact UCL to verify that this is in fact a US EIN.
