There is a $20/day registration fee payable in cash or check (payable to Princeton Univerisity). This fee is waived for Postdocs and graduate students.
Attendees who have been offered support should keep two rules in mind. Reimbursement for air travel can only be made for travel on US Flag Carriers, REGARDLESS OF COST. (For example, travel on airlines such as United, Continental, USAir, and others that are United States based are allowable. Travel on airlines such as Lufthansa, SAS, Air Canada and other airlines based outside the US cannot be reimbursed by DIMACS.)
The second rule to keep in mind is to get original receipts for all reimbursable expenses.
