Tell us the following:

What do you need covered? (Please estimate the costs in USD: hotel $X, travel $Y.)
Travel and hotel

Travel: Depart May 20. Return May 25 - Costs range from approx USD $1230 onwards for an AirCanada flight of manageable duration (~20 hours). Other carriers are either too expensive or too long (30 hours+ journey time).

Hotel: I can share a room with Ankur Sinha till 25th. However I will check-in on 21st. I am not exactly sure about the costs. A cheap one would do just fine.

So total may be something like $1300 + approx. $200 = $1500 USD

If we cannot provide a full subsidy, will a partial subsidy be helpful? (Yes/No??)
Yes.

If Yes, specify the minimum amount you need covered to facilitate your attendance.
I can manage around $200 + local travel + some food by myself.

What will you accomplish by being at FUDCon? (Please be as specific as possible, since this is the most important factor in granting requests.)
I shall be giving a talk titled "Kernel and Userspace Tracing with
LTTng, GDB and friends" where I will discuss various tracing tools and their possible use for Fedora developers.The second hackfest is about Fedora Design and Packaging 101 which may be merged with Ankur Sinha's ROS packaging session. If we have a separate Fedora booth in Gnome.asia, I can man the booth for a few hours too.

If you are requesting airfare, include complete flight information such as flight numbers, desired departure and arrival airports, and times. Also let us know if you have specific time restrictions.

Please refer attached PDF.

Restrictions : I have to depart Beijing by 25th and '''reach Montreal on 26th May positively.''' Its the ultimate constraint for my trip.

Do you need a visa or other official processing before you can attend FUDCon? If so, approximately how long does that processing take?

Yes. It seems I need a F visa. Refer [1]. I do not know how long it takes in Montreal. I know for sure that the 3-5 days fast visa policy is not applicable to foreign nationals in Canada. So it may take some weeks.

Include any additional, relevant information.
A visa support letter on RH letterhead with a valid signature (the same way we had for FUDCon Pune) may be good for easier visa processing. I shall update more details as I find them.
