Q: My paper was published in a journal in 2021 october. But in June 2022, the journal was removed from SCI indexing, what can i do, so much of work in it with two revsions taking more than a year,what can be done

I’m sorry to learn about the situation. However, please do not be discouraged. Being delisted does not mean that the journal can never be a part of SCI again. Journals are delisted from the SCI database if they do not meet all the expected criteria. However, if they improve their standards and meet the criteria next year, they might be indexed once again. Further, it would be a good idea to save a copy of the year of indexing in which your journal was listed and mention your article as "indexed in SCI [year]."
