美国严打中共渗透：从签证到绿卡全面清查🪪
近日，美国对涉嫌与恐怖组织或中共有关的人员采取强硬措施。一名布朗大学教授因疑与「真主党」有联系，入境时被递解出境。
华人律师陈闯创透露，川普上台后，移民法执行更严，国务卿卢比奥称每日撤销签证与绿卡，针对危害外交政策的非公民。曾有亲共者因手机存中共群众照与宣誓证据被拒入境。
川普2020年行政令要求严审与中共相关人士，虽拜登时期没有严格执行，如今重启。申请工卡、绿卡等需提交社媒账号，显示美国对中共渗透的全面清查已启动。

The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
