The USI is calling for changes to students grants, so more people can benefit from them.
The Union of Students says income thresholds need to be raised so more people can qualify for SUSI maintenance grants.
The organisation, representing third-level students, also wants to see Student Contribution Charges reduced by €1,000 as part of tomorrow's Budget.
USI president, Beth O'Reilly, says reform of the student grant system is needed to ease financial pressures for those in third level education.
