The Havana embassy's chargé d' affaires, Timothy Zúñiga-Brown, announced that the consulate would soon begin processing some immigrant visas for which documentation already is complete. He added the US is interested in “safe and legal” immigration, particularly for family reunification cases which had been complicated by the withdrawal of diplomats.

The Cuban government has insisted that there is no scientific evidence to prove the so-called "sonic attack" on American diplomats in the country, saying Havana is ready to cooperate with Washington to clarify the matter.

Cuba accused the administration of then US President Donald Trump of using the incident as an excuse to strain bilateral relations.
