WASHINGTON (Reuters) - Grandparents of U.S. citizens from six Muslim-majority countries are now eligible to receive U.S. visas, according to a State Department memo seen by Reuters that reflects the latest court ruling on U.S. President Donald Trump’s travel ban.

The memo, or cable, from U.S. Secretary of State Rex Tillerson was sent to all U.S. diplomatic posts overseas on Friday after a U.S. district judge in Hawaii issued a ruling late on Thursday limiting the scope of the administration’s temporary ban on refugees and travelers from the six countries.

U.S. District Judge Derrick Watson in Honolulu found the government cannot bar grandparents and other relatives of United States citizens from Iran, Libya, Somalia, Sudan, Syria and Yemen from getting visas under the ban.

Watson declined to put his ruling on hold pending appeal, meaning it went into effect immediately. The administration has asked the Supreme Court and the San Francisco-based 9th U.S. Circuit Court of Appeals to block the decision.

The July 14 cable updated the definition of "close family" that are exempt from the temporary travel ban laid down in Trump's March 6 executive order. (The cable can be read at: reut.rs/2uC040y)

The cable reversed the State Department’s previous, narrow definition of close family and stated that “grandparents, grandchildren, brothers-in-law, sisters-in-law, aunts and uncles, nephews and nieces, and cousins” are eligible for visas.

Consulates and embassies do not need to reopen any visa applications refused under the prior, narrower definition of close family members, the cable said.

Between March 10 and March 17, Tillerson issued four cables, originally giving instructions on implementing the travel ban, then rescinding much of his guidance because of court rulings and because it had been issued without approval from the White House Office of Management and Budget.

In another reversal, the State Department had originally interpreted the Supreme Court’s June 26 ruling to exclude fiancés, saying they do not count as a close family relationship eligible for an exemption to the travel ban. Just before the 90-day travel ban was to take effect on June 29, the State Department said fiancés would be counted as close family.

“These guys (consular officers) have had enough whiplash over the past six, seven months but they continue to fulfill their role, which is to process visa applications,” said Stephen Pattison, a former State Department consular official now working as an immigration attorney. “The people who are really getting whiplash are the people in the department who are responsible for formulating the policy, getting it approved and getting it sent out.”

A State Department official declined to comment on internal communications.

“We regularly provide updated operational instructions to our embassies and consulates around the world to ensure that our consular officers are using the most up-to-date vetting procedures as they adjudicate visas,” the official said on condition of anonymity.

“We are processing visa applications for nationals of the six affected countries as directed by the Executive Order and to the extent permitted by court decisions,” the official said.

Last month the Supreme Court partially revived the March 6 ban that had been blocked by lower courts. It said the ban could take effect, but people with a “bona fide relationship” to a U.S. person or entity could not be barred.
