Somewhat annoyingly, this is the definition of long term immigrant per UN definitions cited in the report includes students:

"The use of the UN definition of long-term immigration means that whether someone should be counted as an immigrant or emigrant (and hence contribute to the net migration statistics) only becomes evident after 12 months.... Currently, the ONS publishes provisional estimates with a 5-month lag"

The discussion of international students is less relevant to employment related concerns, but still contributes to other aspects of population growth like rental housing demand or water consumption.
