The right-wing Fidesz party has long lobbied the EU to take a harder stance on immigration into the continent-wide bloc.
Analysts say that development funds from the EU have been critical in explaining the Fidesz party's success in Hungary.
Experts says the populist leader continues to use the immigration hot button to make the European parliament 'more conservative.'
The new law 'STOP Soros' makes it more difficult for refugees and immigrants to gain asylum in Hungary and threatens people helping asylum seekers with up to a year in prison.
The measure is part of a campaign against US financier George Soros, who is accused of plotting to undermine the country's Christian culture by flooding it with immigrants by funding liberal causes.
Viktor Orban will be formally re-elected for a third straight term as opposition plans to hold a protest demonstration outside the country's parliament on Tuesday evening.
Hungarian Prime Minister Viktor Orban has long been at odds with Soros' network of NGO's which promote liberal values around the world and has blamed the Hungarian-born US financier for a host of ills.
Those on the list published by the weekly Figyelo include members of rights organisations, anti-corruption watchdogs, refugee advocates, investigative journalists and university staff, as well as some people who are already deceased.
Victor Orban will likely seize on the election results as vindication of his clashes with EU institutions over his hardline anti-immigration policies and rejection of the EU's refugee resettlement programme.
Opinion polls have consistently put firebrand nationalist Prime Minister Viktor Orban and his right-wing Fidesz party 20 or more points clear of their nearest rivals, Jobbik, a far-right party that has been moving towards the centre.
Viktor Orban's Fidesz, with a firm grip on the media, dominates the public agenda. All polls predict a win for him on Sunday though something short of the landslides of elections in 2010 and 2014.
Prime Minister Orban, seeking a third term in office, has fixed the economy but unwound democratic freedoms. His opposition to migration has earned him success at home but sown distrust in the EU.
