Will foreign investments affect my TS?

It may or may not affect it negatively. However....you BETTER report any foreign investments. For if you do invest in foreign companies and NOT report it....then that WILL affect your TS in a negative way. You want the best answer on this....then you need to seek out your Security Manager.

SGT (Join to see), The issue isn't whether or not you invest, it is if you don't disclose and don't invest responsibly.

When you rectify your TS, you must disclose changes in your investments if they include in foreign markets. This may, by itself, trigger a deeper dive into the investments themselves. While you may be playing the market, it is not assumed that the investor is picking vehicles at random. So if one of the companies are listed as a bad actor, involved in illicit or illegal activity, connected to or is itself a national security threat, it may delay your recertification. If you are doing fractional or P2P lending, the number of companies (or individuals) you are vested in can get quite long.

The bigger question is why P2P over traditional investment vehicles? 401K/ORP/ and BRS can return upwards of 15% without the national security interest issue. You can get that in P2P, but not without much more exposure to investment risk. Some of those companies are dealing with sub-par lenders that lend to anyone and let these loans go way into default and now your principal is tied up. Additionally, Mintos is global, so you have the currency exchange rate to factor into any loss/gains, which may affect it exponentially.

It could be an issue depending on the specifics. I'd be careful.
