MOSCOW — The members of Russia’s lower house of Parliament — which last year passed so many harsh new laws with so little debate that commentators compared it to a “rabid printer” — returned to work last week as the standard-bearers for President Vladimir V. Putin’s brand of patriotism.

Having captured the world’s attention in December by banning all adoptions of Russian children by American families, members of Parliament have dreamed up a variety of further proposals to purge Russian politics and civic life of foreign influences.

Among them: A full ban on all foreign adoption. A requirement that the children of Russian officials return directly to Russia after studying abroad, lest their parent lose his or her post. A requirement that officials’ children be barred from studying abroad altogether. A requirement that movie theaters screen Russian-made films no less than 20 percent of the time, or face fines as high as 400,000 rubles, or about $13,000.

One group of legislators is working on a bill that would prevent anyone with foreign citizenship, including Russians, from criticizing the government on television. One proposal would ban the use of foreign driver’s licenses, another would require officials to drive Russian-made cars. One deputy has recommended strictly limiting marriages between Russian officials and foreigners, at least those from states that were not formerly Soviet.
