No. The European Parliament and the Council have agreed on a Regulation to ensure that ongoing learning mobility exchanges are not interrupted.

The Regulation would apply to students in higher education, apprentices and pupils in vocational education and training, young people in non-formal learning activities, staff in education and training, persons active in youth work and youth leaders.

You should note, however, that the Regulation only covers learning exchanges starting before the withdrawal date.

Your plans for learning exchange might be affected. However, the Commission has presented a legislative proposal that would, if adopted, enable the EU to continue funding Erasmus+ in the UK during 2019. Whether you can go ahead would depend on a number of factors, e.g. that the UK continues to pay to the EU budget for 2019, on the UK host organisations (in your case the university) and on whether the activities end by 31 December 2019. You should check this directly with the university.

The cooperation project might be affected since, as of the withdrawal date, the UK partner will no longer be eligible for funding under Erasmus+.

However, the Commission has presented a legislative proposal to address the situation. If that proposal is adopted and if the United Kingdom fulfills certain conditions, the project could continue to be financed in 2019. You should check this with your Erasmus+ National Agency

However, the Commission has presented a legislative proposal to address the situation. If that proposal is adopted and if the United Kingdom fulfills certain conditions, the project could continue to be financed in 2019.

You should check this with the Creative Europe desk in your Member State.

Your research project might be affected since, as of the withdrawal date, the UK organisation will no longer be eligible for EU funding under the Marie Skłodowska-Curie actions.

However, the Commission has presented a legislative proposal to address the situation. If that proposal is adopted and if the United Kingdom fulfills certain conditions, the project could continue to be financed in 2019.

You should note that Marie Skłodowska-Curie actions will continue to support researchers in a EU4 Member State or a non-EU country that is associated with the Horizon 2020 programme.

You should check this with your supervisor and the dedicated project officer at the European Commission’s Research Executive Agency.

Your placement under the European Solidarity Corps might be affected since, as of the withdrawal date, the UK organisation will no longer be eligible for funding under that programme.

You should check this with the organisation providing the funding for your placement.
