Surviving spouses of US citizens may now apply for a green card under new guidelines. The US Citizenship and Immigration Services (USCIS) has outlined six specific conditions that must be met. These include maintaining a valid marriage and proving the relationship was genuine. Applicants must also demonstrate they are admissible to the US. The new rules aim to ensure the integrity of the green card process. Eligibility is tied to the death of a US citizen spouse. The guidelines clarify the documentation needed for each condition. This update affects those who lost their spouse and wish to remain in the US. The changes reflect ongoing efforts to refine immigration policies.
