Two proposals were put to voters – one to reduce the number of MPs in the Seimas from 141 to 121 and one to allow Lithuanians to hold dual citizenship with a list of countries meeting "European or transatlantic integration criteria," which would be determined by law.

The proposal on dual citizenship had a turnout of over 50% and was approved by 73% of those voting, but this amounted to only 38% of eligible voters.

[3] The proposal to allow dual citizenship was approved by a vote in the Seimas in October, and would involve amending article 12 of the constitution.

[1] In a draft constitutional law that sat alongside the proposal, this would be limited to member countries of the European Union, European Economic Area, NATO and the OECD and explicitly prohibit dual citizenship with countries involved in organisations based around the former Soviet Union, including the Commonwealth of Independent States, Collective Security Treaty Organization and Eurasian Economic Union.

[2] An amendment to the Law on Referendums approved by the Seimas in December 2018 allowed polling places to be set up in foreign countries.
