We're coming up into the marriage season, and just a friendly piece of advice for those applying abroad for spousals (i.e., the VAF2).
You want to be sure to fix your itinerary so that you arrive in the UK within 4 weeks of the start date of your entry clearance. That's the slack period that they give you.
If you don't arrive within that period, you won't get in trouble. It doesn't have to do with being in trouble or not. It just means that you might have to pay for an LLR extension when your probationary visa expires. And then cough up some more money to get your ILR - EVEN ON THE NEXT DAY!!!

And the way things are going, that could be pricey - and who wants to throw an extra £500 away because they didn't plan ahead? They have been getting persnickety about ILR apps from spouses on LLR.
On a different topic, but related to being persnickety, for those submitting nationality apps, take note that Liverpool is persnickety about your start date. It's calculated to be exactly and exactly 3 years prior to the day they stamp it RECEIVED in their mail room - and if you were not in the UK on that exact day, your app will be misconceived. And in summary, that means the post office introduces an element of randomness into people's start dates. This only affects a small amount of people, but it pays to be careful!
