I received a request for further documentation on 7 of February, I sent it on Friday and they received on the following Tuesday (registered letter). I didn't receive any letter from them acknowledging that the documentation was received.
As we have 28 day to reply or the application is withdrawal, should/do I need to contact them to confirm? Or just wait ?
28 day will be only on the first week of March, but I will be travelling. So, if you have an advice. Thank you
