Answer the question at the end by quoting:

Joseph Conrad (Polish pronunciation: ['juzef ,kon.rad]; born Jozef Teodor Konrad Korzeniowski; 3 December 1857 - 3 August 1924) was a Polish-British writer regarded as one of the greatest novelists to write in the English language. He joined the British merchant marine in 1878, and was granted British citizenship in 1886. Though he did not speak English fluently until his twenties, he was a master prose stylist who brought a non-English sensibility into English literature. He wrote stories and novels, many with a nautical setting, that depict trials of the human spirit in the midst of an impassive, inscrutable universe.
Conrad was a Russian subject, having been born in the Russian part of what had once been the Polish-Lithuanian Commonwealth. In December 1867, with the Russian government's permission, his father Apollo had taken him to the Austrian part of the former Commonwealth, which enjoyed considerable internal freedom and a degree of self-government. After the father's death, Conrad's uncle Bobrowski had attempted to secure Austrian citizenship for him - to no avail, probably because Conrad had not received permission from Russian authorities to remain abroad permanently and had not been released from being a Russian subject. Conrad could not return to Ukraine, in the Russian Empire - he would have been liable to many years' military service and, as the son of political exiles, to harassment. In a letter of 9 August 1877, Conrad's uncle Bobrowski broached two important subjects: the desirability of Conrad's naturalisation abroad (tantamount to release from being a Russian subject) and Conrad's plans to join the British merchant marine. "[D]o you speak English?... I never wished you to become naturalized in France, mainly because of the compulsory military service... I thought, however, of your getting naturalized in Switzerland..." In his next letter, Bobrowski supported Conrad's idea of seeking citizenship of the United States or of "one of the more important Southern Republics". Eventually Conrad would make his home in England. On 2 July 1886 he applied for British nationality, which was granted on 19 August 1886. Yet, in spite of having become a subject of Queen Victoria, Conrad had not ceased to be a subject of Tsar Alexander III. To achieve the latter, he had to make many visits to the Russian Embassy in London and politely reiterate his request. He would later recall the Embassy's home at Belgrave Square in his novel The Secret Agent. Finally, on 2 April 1889, the Russian Ministry of Home Affairs released "the son of a Polish man of letters, captain of the British merchant marine" from the status of Russian subject.

why was he stuck

Conrad could not return to Ukraine, in the Russian Empire - he would have been liable to many years' military service and, as the son of political exiles, to harassment.

IN: Lieberman was born in Stamford, Connecticut, the son of Henry, who ran a liquor store, and Marcia (nee Manger) Lieberman. His family is Jewish; his paternal grandparents emigrated from Congress Poland and his maternal grandparents were from Austria-Hungary. He received a B.A. in both political science and economics from Yale University in 1964 and was the first member of his family to graduate from college. At Yale he was editor of the Yale Daily News and a member of the Elihu Club.

Lieberman was one of the Senate's strongest advocates for the war in Iraq. He is also an outspoken supporter of the U.S.-Israel relationship. On domestic issues, he strongly supports free trade economics while reliably voting for pro-trade union legislation. He has also opposed filibustering Republican judicial appointments. With Lynne Cheney and others, Lieberman co-founded American Council of Trustees and Alumni in 1995. Lieberman is a supporter of abortion rights and of the rights of gays and lesbians to adopt children, to be protected with hatecrime legislation, and to serve openly in the military. Lieberman was one of the Senate's leading opponents of violence in video games and on television. Lieberman describes himself as being "genuinely an Independent," saying "I agree more often than not with Democrats on domestic policy. I agree more often than not with Republicans on foreign and defense policy." Lieberman is also famous for championing, authoring and leading the effort that led to the repeal of Don't ask, don't tell. During debate on the Patient Protection and Affordable Care Act, Lieberman opposed the public option. As the crucial 60th vote needed to pass the legislation, his opposition to the public option was critical for its removal from the resulting bill. Lieberman was an integral part in attempting to stop WikiLeaks from publishing further material using U.S.-based corporations in the United States diplomatic cables leak of 2010. In June 2015, Lieberman was a signatory to a public letter written by a bipartisan group of 19 U.S. diplomats, experts, and others, on the then-pending negotiations for an agreement between Iran and world powers over Iran's nuclear program. That letter outlined concerns about several provisions in the then-unfinished agreement and called for a number of improvements to strengthen the prospective agreement and win the letter-writers' support for it. The final agreement, concluded in July 2015, shows the influence of the letter. On May 17, 2017, it was reported that Lieberman was a frontrunner to replace FBI Director James Comey, who was fired by President Donald Trump on May 9, 2017.
