Does a consular official have access to an arrested foreign national for visits, calls, and writing?

A consular official has the right to access an arrested foreign national for visits, phone calls, and writing correspondence as part of their diplomatic rights under international law. These rights are generally outlined in various treaties, such as the Vienna Convention on Consular Relations, which establishes that arrested individuals have the right to communicate with their consulate, allowing for visits and communication methods to ensure the detained person's welfare and legal representation. This system of access is in place to protect the interests of foreign nationals while also facilitating necessary legal and humanitarian support. Therefore, it is correct to state that all forms of access are permitted for consular officials in this situation.
