First you realise that you will only be filling out information online. While the form does help you prepare, the online application does differ from the application and takes care of some of the "illogical" questions you mention below, where the paper form has to accomodate for a lot of different circumstances that can be addressed with an interactive form.
- Part 4 Your Family 4.11 - 4.15
Even though I am the sponsor, am I correct to assume my details should be filled here as the spouse?
Yes.
- Part 5 Finances and Employment
We are getting married on 4th April but applying in March so we can complete the biometrics before the wedding and send of the postal application with the marriage certificate straight away. Molly will be employed until the end of March when she'll resign to get married, go on honeymoon and move to the UK.
So the question is should she fill in her job details as we're applying electronically in March or put unemployed as she will be when the postal application goes in?
If she doesn't fill it in should she put her salary in the Income and Expenditure section as she will be paid at the end of March and be bringing some of that money with her?
The situation at the point where you fill out the form.
Question 8.2.8 - Where is your sponsor now?
I assume the correct answer is "In the USA with me on honeymoon" or is the point of the question to state I am settled in the UK? As I won't be physically in the UK should I leave 8.2.9 blank or fill in my date of birth?
Wherever you are. As far as settled, you can still be settled in the UK if you are present, so "whole life" or your data of birth is acceptable.
Question 8.2.8 - When did you last see you sponsor?
I assume "He is with me currently is the correct reponse"?
Yes.
Question 8.7.7 - What is their employer's email address?
Is a HR address or my boss' address best here?
Best to focus on HR. They are unlikely to check anything anyways, but if they do, it shoudl be someone in the posistion to verify something.
One final question regarding the fee increase in April. We will apply online and pay in March before the increase but the wedding and postal application will be in April after the increase - Is it likely to be refused due to the incorrect fee or would they ring to arrange balance payment?
Not 100% sure, but I think when you fill out and pay in March to do the biometrics and send the packet in April.
