In the context of a United Nations gathering, there are discussions about possible restrictions that could prohibit Iranian individuals from making purchases at Costco.

The United States government is considering imposing travel restrictions on several UN delegations, including those from Iran, Sudan, Zimbabwe, and Brazil. According to reports, these restrictions could limit the diplomats' movements within New York City, potentially banning them from shopping at wholesale stores such as Costco and Sam's Club.

The proposed restrictions are not new to the diplomatic world. In the past, the Trump administration has denied visas for Palestinian leader Mahmoud Abbas and his delegation to attend a high-level UN meeting. Similarly, the Syrian delegation has been subject to limitations on their UN travel for over a decade, a waiver that was issued last week as the Trump administration seeks to build ties and integrate Syria into the Middle East following the ouster of President Bashar Assad.

The proposed restrictions for the Iranian, Sudanese, and Zimbabwean delegations are not yet clear. The State Department is considering drafting rules that would allow it to impose terms and conditions on memberships in wholesale clubs by all foreign diplomats in the US. However, the exact countries for the NYC travel restriction are not explicitly listed in available sources.

It is unclear if any potential visa restrictions affect President Luiz Inácio Lula da Silva or lower-level members of the Brazilian delegation to the UN gathering. Brazil's president is traditionally the first world leader to speak before the gathered officials on the opening day of the UN session, a position that Lula would hold if the restrictions do not prevent him from attending.

The US president is by precedent the second speaker at the UN session. Brazil's prominent role in the UN is not new, with its president traditionally holding a significant position in the international community.

The Iranian and Brazilian UN missions did not immediately reply to requests for comment regarding potential restrictions. The State Department is not providing comment on the potential restrictions for the Sudanese and Zimbabwean delegations.

The proposed restrictions come amidst ongoing tensions between the US and these countries. Lula has been a target of US President Donald Trump due to his government's prosecution of former President Jair Bolsonaro on allegations of leading an attempted coup. Similarly, the governments of Sudan and Zimbabwe have faced sanctions from the US in the past.

These potential travel and other restrictions could significantly impact the UN meetings, potentially disrupting diplomatic discussions and negotiations. As the situation develops, more information is expected to be released.
