Thank you for your response. Spouse's I-485 & I-765 are pending adjudication since May 2017 and she just received an interview date for next month.There is no need. A widow(er) of a US citizen can self-petition (with I-360) for permanent residency within 2 years of the US citizen's death, as long as they have not remarried. If the US citizen dies while the I-130 is pending or approved, it will automatically be converted to an I-360 without needing to file one separately.
