2012–2016

Imamović received the third position on the SDA's electoral list in the 2012 Serbian parliamentary election. The party won two mandates; Imamović was not immediately elected but was awarded a seat on 25 July 2012 as the replacement for Ifeta Radončić, who had resigned on the same day the assembly convened.^[7][8][9] The SDA initially served in an assembly group with the People's Party (NP); Maja Gojković was the group's leader, and Imamović was its deputy leader.^[10] This arrangement did not last, and the SDA deputies afterward served on their own, without affiliation to any assembly group. In this sitting of parliament, Imamović was a member of the parliamentary friendship groups with Azerbaijan, Bosnia and Herzegovina, France, Germany, Turkey, United Kingdom, and the United States of America.^[11] The SDA was part of the government during this time, and he served as a supporter of the administration.

Imamović was promoted to the second position on the SDA's list for the 2014 parliamentary election and was re-elected when the party won three seats.^[12] After the election, the SDA left the government and moved into opposition, forming an assembly group with the Party for Democratic Action (PDD), a party representing Serbia's Albanian community. In his second term, Imamović was a member of the committee for the economy, regional development, trade, tourism, and energy; a deputy member of the committee for labour, social affairs, social inclusion, and poverty reduction; a deputy member of Serbia's delegation to the Parliamentary Assembly of the Mediterranean; and a member of the friendship groups with Algeria, Austria, Azerbaijan, Bosnia and Herzegovina, China, Croatia, the Czech Republic, France, Germany, India, Indonesia, Iran, Kuwait, Lebanon, Luxembourg, the Republic of Macedonia, Montenegro, Morocco, Russia, Saudi Arabia, Slovakia, Slovenia, Tunisia, Turkey, the United Kingdom, and the United States.^[13] In 2014, he proposed a type of autonomy for the Sandžak similar to that of South Tyrol within Italy.^[14]

Imamović again received the second position on the SDA's list in the 2016 parliamentary election and was elected for a third term when the party won two seats.^[15] The SDA sat in an assembly group with the Liberal Democratic Party (LDP) and the League of Social Democrats of Vojvodina (LSV), and Imamović became the group's deputy leader. In this parliament, he was a member of the committee on human and minority rights and gender equality; a member of the committee on labour, social issues, social inclusion, and poverty reduction; a deputy member of the committee for culture and information and the committee on the rights of the child; a member of a working group for the rights of minorities; a member of Serbia's delegation to the Parliamentary Assembly of the Mediterranean; and a deputy member of its delegation to the parliamentary dimension of the Central European Initiative.^[16][17]

He was promoted to the lead position on the SDA's list in the 2020 Serbian parliamentary election and was elected to a fourth term when the party won three mandates.^[18] The SDA afterward formed an assembly group with the Albanian Democratic Alternative (a coalition led by the PDD), and Imamović once again served in the role of deputy leader. He was a member of the committee for European integration; a deputy member of the labour committee; the president of Serbia's parliamentary friendship group with Luxembourg; and a member of the friendship groups with Albania, Algeria, Austria, Azerbaijan, Belgium, Bosnia and Herzegovina, Canada, Croatia, France, Germany, Indonesia, Montenegro, Norway, Palestine, Portugal, Slovenia, Sweden, Switzerland, Turkey, the United Kingdom, and the United States.^[19]

He was also appointed as a member of Serbia's delegation to the Parliamentary Assembly of the Council of Europe (PACE) on 25 January 2021. In the PACE, he was a full member of the committee on social affairs, health, and sustainable development; and a full member of the committee on migration, refugees, and displaced persons. He did not serve with any parliamentary grouping.^[20]

2022 election and after

Imamović again appeared in the lead position on the SDA's list in the 2022 Serbian parliamentary election and was re-elected when the list won two seats.^[21] After the election, the SDA became part of an assembly group called European Regions, which also included delegates from Vojvodina and from Serbia's Albanian community. Imamović was the group's deputy leader.^[22] The group ceased to exist when one of its members, Tomislav Žigmanov, was appointed as a minister in the Serbian government.^[23] The SDA delegates are not currently members of any assembly group.

Imamović is now a member of the environmental protection committee, a deputy member of the health and family committee, a member of Serbia's delegation to the South-East European Cooperation Process parliamentary assembly, and a member of the parliamentary friendship groups with Albania, Austria, Azerbaijan, Belgium, Bosnia and Herzegovina, Croatia, France, Germany, Indonesia, Montenegro, Norway, Palestine, Slovenia, Spain, Switzerland, Turkey, Ukraine, the United Kingdom, and the United States.^[24] His term in the PACE ended on 9 October 2022.^[25]
